报告摘要：

Due to impending depletion of fossil-based energy resources and strict environmental law, people are looking for new energy resources and greener processes, where heterogeneous catalytic systems play an increasingly important role. Nano-sized metal oxides and supported metal nanocatalysts, which are characteristic of cleaner and much highly selective, have been regarded as the most promising potential to replace toxic and corrosive liquid catalysts in most of chemical processes. However, how to improve activities and selectivity of nanocatalysts for the desired products still remains a serious challenge. There is close interaction between reactants and catalytically active sites, which determines the ultimate performance of the latter. Based on understanding the catalytically active species and their functions, it is possible to design and control catalytic properties of catalysts at the nanoscale level for desired reactions. This more strategic approach will promote nanocatalyst development and provide an alternative to the classical trial-and-error approach, with prospects for viable pre-design. In addition, in-situ spectroscopic techniques can provide specific information about working catalysts, reaction pathways, and kinetics, offering the essential parameters for reactor and process design and modulation. It bridges the gap between fundamental molecular-scale studies and realistic chemical processes, and will realise chemical engineering design from atomic level to macro level.
