Abstract
Mesoporous metals have attracted extensive attention in electrocatalytic oxidation of methanol owing to their high conductivity, large surface area, and pore volume, which can provide rich and accessible active sites for guest species. In this mini review, we mainly focus on the recent advances of the synthetic strategies of mesoporous metals and their applications in the catalytic oxidation of methanol. The underlying mechanism for both the hard and soft-templating method was first discussed. Then, the influence of morphology, structure, and composition of mesoporous metal and its alloy catalysts on the catalytic activity of methanol oxidation was highlighted. Precious design of the morphology and composition of Pt-group-based alloy electrocatalysts represents an important route to enhance catalytic activity and stability due to the improved tolerance of Pt in intermediate CO in methanol oxidation. Finally, the review is ended with a conclusion and future perspective.
