Since the discovery of catalysis by Au nanoparticles (NPs), unique catalytic features of Au
have appeared that are greatly different from those of Pd and Pt. In this Review, we aimed to …

Many natural oxidations are relevant to the origin and running of life but usually proceeded
under mild conditions using molecular oxygen (O2) in the air as the sole oxidant and …

Preferential oxidation of CO (PROX) in H2-rich stream is critical to the production of clean H2
for the H2-based fuel cells, which provide clean and efficient energy conversion …

Supported gold (Au) nanocatalysts have attracted extensive interests in the past decades
because of their unique catalytic properties for a number of key chemical reactions …

Industrial hydrogen production through methane steam reforming exceeds 50 million tons
annually and accounts for 2–5% of global energy consumption. The hydrogen product, even …

Water adsorbed at the metal–support interface (MSI) plays an important role in multiple
reactions. Due to its importance in CO preferential oxidation (PrOx), we examined H2 …

The mechanism of CO oxidation over supported gold catalysts has long been debated, with
two prevailing mechanisms dominating the discussion: a water-assisted mechanism and a …

Preferential oxidation of CO (PROX) in a H2-rich stream is considered as a promising
strategy for abatement of trace amounts of CO to prevent poisoning of Pt anodes by H2 in …

Hydrogen purification is essential to satisfy the various purity requirements for different
applications. Preferential oxidation of carbon monoxide (CO-PROX) is a promising strategy …

Abstract Au/CeO 2 (0.25% wt. Au) catalysts were prepared by anchoring preformed Au
nanoparticles over ceria polycrystals, cubes and rods and tested in the oxidation of CO and …
