Photocatalytic methods can be operated remotely and initial studies show minimal production of undesired side products. Studies using titania alone as a photocatalyst show limitations, not only in terms of the slow rate of photoreduction of nitrate but also in terms of selectivity and the need to employ radiation in the UV region due to the magnitude of the band gap.

His research interests include: use of vibrational spectroscopy to examine surfaces and interfaces, with a focus on hydrocarbon including biomass activation reforming and hydroisomerisation , acetylene, alkyne and carbon monoxide hydrogenation and photocatalytic water treatment. As the global demand for plastics is set to triple over the next 30 years, decoupling plastics production from fossil feedstocks will become an increasingly important challenge.

Therefore, the use of bio-based resources for the production of plastics is highly active area of research in both academia and industry. Polylactide PLA , produced via the catalytic ring-opening polymerization ROP of lactide, is one of the most promising alternatives to petrochemically-derived plastics for commodity applications such as packaging and fibres. Progress in developing new stereoselective catalysts for ROP of lactide has been impressive, but industrial application of these catalysts is currently limited.

This talk will focus on the development of zirconium-based catalysts for industrial PLA production. The design of new stereoselective catalysts, understanding of the mechanism of stereocontrol and the development of new synthetic strategies for control of polymer architecture will be discussed in the context of broadening the scope of PLA as a commodity bio-based plastic.

His research focuses on the application of molecular chemistry and catalysis to sustainable chemical processes such as manufacture of renewable fuels, chemicals and plastics. Biocatalysis uses enzymes for chemical synthesis and production, offering selective, safe and sustainable catalysis. While today the majority of applications are in the pharmaceutical sector, new opportunities are arising every day in other industry sectors, where production costs become a more important driver.

In the early applications of the technology it was necessary to design processes to match the properties of the biocatalyst. With the advent of protein engineering that paradigm has changed into one where the biocatalyst can be designed to match the process. Progress has been spectacular, but in recent years the route to industrial implementation has become increasingly dependent upon timely protein engineering to enable the tailored design of a given biocatalyst.

Today a new era is entered, where the effectiveness with which such protein engineering is achieved becomes critical to implementation. In this lecture two methods to improve this will be described.

Public Lecture - Catalysis: the Hidden Path to Foods, Fuels and Our Future

The first involves the development of target-setting based on process requirements to guide protein engineering. The second involves the simultaneous solution of the biocatalyst and process design problems. Illustration of both approaches will be given in the lecture. His research is focused on bioprocess engineering, design, intensification, scale-up and implementation.

Aside from experimental studies the group also has interests in thermodynamics and kinetic modelling as tools to assist in techno-economic evaluation of bioprocesses. He has published over ISI journal papers, 60 conference proceedings, 20 book chapters and conference abstracts. He sits on several scientific advisory and editorial boards.

This talk will highlight principle strategies and current challenges in enzyme discovery and protein engineering. For the synthesis of chiral amines, Bornscheuer performed an in silico analysis and identified a toolbox of novel R -selective ATAs as well as S -selective enzymes from a structure-guided search.

More recently, his group could engineer S -selective ATA for the acceptance of bulky ketones for the asymmetric synthesis of a set of important chiral amines. Uwe T Bornscheuer studied chemistry and completed his doctorate in at the Uni-versity of Hannover Germany.

He then performed a postdoc at the University of Nagoya Japan. In , he completed his Habilitation at the University of Stuttgart Germany. In , he received the BioCat Award for his innovative work on tailored biocatalysts for industrial applications and several awards Normann Medal, Chevreul Medal, Stephen S. Chang Award for his achievements in the area of enzymatic lipid modifications. His current research interest focusses on the discovery and protein-engineering of various enzymes for organic synthesis and lipid modification using methods ranging from rational protein design to high-throughput screening methods for biocatalyst discovery including the development of enzyme-cascade reactions.

Biomass presents a promising renewable feedstocks for production of fuels and chemicals. In recent years, the interest in a tailored valorisation of lignocellulose, the major component of biomass, has increased significantly. However, selective transformations are hampered by the high degree of functionalization of renewable feedstocks. Indeed, solid catalysts in current refinery technologies have been optimized to functionalize non-polar substrates in gas-phase reactions at elevated temperature.

In contrast, renewable feedstocks exhibit a multitude of functional groups necessitating selective de-functionalization strategies in low-temperature liquid phase reactions with high polar solvents. Concepts such as selective adsorption, deoxydehydration as novel catalytic strategy, as well as solid molecular catalysts in H 2 production from formic acid as well as CO 2 activation will be discussed.

Afterwards, she joined the group of Professor Bert Weckhuysen at Utrecht University as a postdoctoral fellow. Computer modelling is an extremely useful tool to investigate structures and processes that are inaccessible experimentally and to help interpret experiment. Furthermore, computational techniques are increasingly truly predictive in identifying promising materials and processes for specific applications.

Main targets

Here, de Leeuw presents a computational study of promising catalysts for sustainable energy production. Carbon dioxide capture and utilisation is gaining significant attention, not only driven by environmental factors but also by the potential to exploit it as chemical feedstock. One plausible utilisation route is its conversion to small organic molecules as pre-cursors to fuels and chemicals, but CO 2 is thermodynamically very stable and its reduction is energy-intensive.

However, CO 2 conversion does take place under mild conditions in chemoautotrophic bacteria catalysed by enzymes.

These enzymes often contain Fe 4 S 4 cubane clusters, which have been shown to act as electron-transfer sites, but they can also be catalytically active centres for molecule transformations. A number of iron sulphide mineral are structurally similar to this cluster — a fact that suggests that they may well be a suitable heterogeneous catalyst.

  4. Here, de Leeuw presents a combined theoretical and experimental investigation of cubane-structured iron sulphide minerals as potential catalyst in the transformation of CO 2 into organic molecules. Professor Nora de Leeuw is a prominent scientist with an international reputation in the field of computational chemistry of materials and minerals. Specific research interests include the development of models to study biocompatible materials for tissue engineering applications, and the computer-aided design of sustainable catalysts for the conversion of carbon dioxide to fuels and chemicals under mild reaction conditions.

    Catalysis plays a central role in delivering materials from renewable resources and this lecture addresses the alternating copolymerization of epoxides and carbon dioxide. Central to applying such materials is to understand and improve the physical-chemical properties.

    Catalytic Conversion of Carbohydrates to Initial Platform Chemicals: Chemistry and Sustainability.

    Here, the opportunity to use homogeneous catalysts to deliver block sequence controlled materials from mixtures of monomers is examined. The strategy applies a single catalyst and mixtures of epoxides, carbon dioxide, anhydrides and lactones to prepare materials with controllable and predictable block sequences. The factors underpinning catalytic selectivity are examined by both experimental and theoretical methods. Furthermore the catalysis is exploited to prepare oxygenated polymers suitable for higher end commodity applications such as thermoplastic elastomers and shape memory materials.

    The lecture the potential for controlled polymerization catalysis to deliver new sustainable materials showing high performances for a range of applications. Charlotte K Williams Department of Chemistry, Oxford University researches catalysis that allow renewable resources to be used to make polymers, composites and fuels. Her research includes the development of homogeneous catalysts for polymerizations of plant-derived resources and carbon dioxide to deliver oxygenated polymers.

    She also investigates colloidal nanoparticle catalysts for the hydrogenation of carbon dioxide or syn-gas to methanol and dimethyl ether. Developing sustainable processes for industry is a key target for both academic and industrial researchers. There are a small number of large sale chemicals that account for the majority of greenhouse gas emissions from the chemical industry, such as ammonia, ethylene or methanol.

    This talk will discuss the concept of sustainability in an industrial context and highlight progress towards improved sustainability in large scale chemical processes such as methanol synthesis and nitric acid manufacture. In addition to this he has led a product development team based in the UK and USA looking at the scale-up and commercialisation to multi-tonne quantities of new catalysts.
