Catalysts are the enabling technology for conversion and synthesis of energy and chemicals. To increase the sustainability of chemicals and fuels production, new and better processes must be developed, which requires the development of new and better catalysts. Their design is greatly helped by the fundamental understanding of why one catalyst is a better one than another. To this end, in situ...

Catalytic properties of metal clusters exhibit a pronounced size dependence. In general, catalytic properties depend on the chemisorption bond between the molecule (e.g., CO) and the catalyst. One well studied case is the chemisorption of CO to metal surfaces. Depending on the metal, the 4 sigma, 1 pi and 5 sigma orbitals which form the bond show strong variations in binding energy. For...

The elucidation of the size, composition, shape, structure and function relationship, of the effect of support along with the determination and control of the nature of the catalytic particles under reaction conditions are instrumental for addressing fundamental aspects of catalysis on the way to the design and understanding the function of existing and new classes of cluster-based catalytic...

Supported platinum catalysts for the oxidation of carbon monoxide adopt different structures depending on temperature and reactant concentrations. These structures, which show vastly different activity, can be identified by X-ray absorption spectroscopy (XAS). While the low-temperature, low-activity state and the high-temperature, high-activity state are each well characterized, there is...

The conversion and storage of solar energy by generating fuels from H2O and CO2 using thermochemical redox cycles driven by concentrated solar radiation present a viable pathway towards a sustainable and environmentally benign energy future.
A two-step cycle based on non-stoichiometric ceria that requires challenging operation conditions - typically 1773 K for the reduction and 1073 K for...
