▎ 摘　　要

Pt catalysts supported by reduced graphene oxide (Pt/rGO) are expected to be widely used in the anodic methanol oxidation reaction (MOR) for direct methanol fuel cells (DMFCs). However, the Pt/rGO possess problems such as rGO sheets restacking, Pt dissolution and agglomeration, adsorption of CO and other intermediates. In this paper, recent modification strategies of Pt/rGO catalysts in Pt nanocrystals and rGO supports are reviewed, their advantages and existing problems are pointed out, and relevant mechanisms are discussed in detail. Furthermore, challenges and the future development directions of Pt/rGO modifications are summarized and prospected. (c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
