Abstract

Catalysis science research employing model systems (single crystal surfaces) focused on understanding and enhancing catalytic activity (turnover rate). The catalyst surface structure and the mobility of adsorbed species are key ingredients that control activity. Catalytic selectivity is the focus of research in the foreseeable future to develop environmentally benign chemical processes that approach 100% selectivity. The catalyst surface structure, selective site blocking, bifunctional catalysis, and oxide–metal interfaces have been recognized as some of the features of reaction selectivity. New two-dimensional model catalyst systems are being fabricated by electron beam and photolithographies for molecular studies of selectivity. New methods are employed to develop three-dimensional high surface area catalysts with precise control of metal particle size, surface structure, and location in the mezopores.
