Congratulations to Wei and Geoff on their recent publication in Advanced Science and the winner of front cover

Catalyst stability is the most important parameter for industrial application. For example, Cu is a prestigious CO2 catalyst, but its durability is partially limited by the sintering of Cu nanoparticles under high temperature. Increasing the Cu-support interaction can enhance stability, which is typically realized on reducible metal oxides via in-situ migration to partial Cu coverage. In a recent work, Wei and Geoff developed an alternative method to expand the strong metal-support interaction to non-reducible silica supported Cu. Within the novel design, a two-dimensional multi-layer SiO2 support is prepared by topological exfoliation of CaSi2 with CuCl2 and thereafter calcination Cu nanoparticles, and thus Cu nanoparticles are encapsulated and confined between layers. The prepared Cu-SiO2 catalysts exhibit excellent activity and long-term stability in high-temperature CO2 hydrogenation reactions. See full story at Advanced Science.
