Title: CORE-SHELL AND YOLK-SHELL CATALYSTS AND MAKING THEREOF
Abstract:
A supported catalyst having a core-shell or a yolk-shell structure is disclosed. The supported catalyst includes a catalytic metal-containing nano- or microstructure and an etched perforated metal oxide support shell encompassing the catalytic metal-containing nano- or microstructure, wherein the shell comprises silica (Si02), alumina (A1203), or both, and includes apertures where silica (Si02), alumina (A1203), or both, have been etched away from the shell, and wherein the apertures are configured to allow reactants to transverse from outside the shell to the surface of the catalytic metal-containing nano- or microstructure.
