Abstract:
1. A method for making catalytic mesoporous aerogels having three-dimensional nanoarchitecture having individual catalytic metal particles in contact with multiple metal oxide particles, comprising: A. forming a monolayer-protected cluster or ligand-stabilized colloid of a catalytic metal; B. forming a sol of a metal oxide; C. mixing said monolayer-protected cluster or ligand-stabilized colloid of a catalytic metal with said metal-oxide sol, and allowing said sol to form a gel; D. extracting said gel with supercritical carbon dioxide to form an aerogel; E. calcining said aerogel to form said catalytic mesoporous aerogel having three-dimensional nanoarchitecture with said metal cluster distributed therein, wherein individual catalytic metal particles are in contact with multiple metal oxide particles.
