Progress in carbon monoxide oxidation over nanosized Ag catalysts

Nanosized Ag catalysts have attracted much attention because of their unique catalytic properties for various reactions, in particular for CO oxidation at low temperatures. Recently, Ag catalysts displaying high catalytic activities and reaction stabilities, and good application prospects in the elimination of CO, even at ambient temperature, have been developed. In this review, combined with our group's research, the different influencing factors such as the preparation method, support, pretreatment conditions, second component, other atmosphere, and reaction mechanisms are discussed in detail and summarized.
