CO Oxidation Properties and Scanning Transmission Electron Microscopy Observation of Au/SrTiO3 Catalysts

Bottom-up formation of gold truncated pyramids smaller than 10 nm on SrTiO3 nanocubes: an application for plasmonic water oxidation

An atomically commensurate interface gives rise to Au truncated pyramids < 10 nm on single-crystalline SrTiO₃ nanocubes (NCs) in a simple deposition-precipitation process without a surface modifier, and the resulting hybrid nanocrystals exhibit a high level of photocatalytic activity for a plasmonic oxygen evolution reaction at light wavelengths (λ_ex) ≤ 1200 nm.

Catalytic oxidation of CO on noble metal-based catalysts

Carbon monoxide (CO) catalytic oxidation has gained increasing interest in recent years due to its application prospects. The noble metal catalysts commonly exhibit outstanding CO catalytic oxidation activity. Therefore, this article reviewed the recent research on the application of noble metal catalysts in the catalytic oxidation of CO. The effects of catalyst support, dopant, and physicochemical properties on the catalytic activity for CO oxidation are summarized. The influence of the presence of water vapor and sulfur dioxide in the reaction atmosphere on the catalytic activity in CO oxidation is emphatically discussed. Moreover, this paper discussed several reaction mechanisms of CO catalytic oxidation on noble metal catalysts. Finally, the challenges of removing CO by catalytic oxidation in practical industrial flue gas are proposed.
