Abstract:Several examples have been presented to demonstrate a successful translation of the novel concepts of nano-confined catalysis into the real catalytic processes. The concepts shown in the model catalysts are based on the synergetic electorn confinements derived from the channels of carbon nanotubes and the interface between noble-metal and oxides with coordinately unsaturated low valent states. Their realization and application in several catalytic reactions, such as selective oxidation and syngas conversion illustrate a promising and efficient way to design active sites for nanocatalysts.
