Phosphorus is incorporated into graphene (PG) by thermal treating method, which is further employed as supports for Pt nanoparticles. The as-obtained Pt/PG catalyst exhibits over 2.4 times enhanced methanol electrooxidation activity compared with Pt/C, as well as desirable stability and remarkably improved CO-tolerance. These improvements are attributed to not only uniformly dispersed Pt nanoparticles that are anchored by introduced defects in PG, but also negative d-band center shift and weakened CO adsorption on Pt caused by strong interactions between Pt and PG. Consequently, PG is a promising support material for Pt-based catalysts towards methanol electrooxidation.

磷掺杂的石墨烯载体可增强铂纳米颗粒上甲醇氧化反应的电催化

通过热处理方法将磷掺入石墨烯（PG）中，并进一步用作Pt纳米颗粒的载体。与Pt / C相比，如此获得的Pt / PG催化剂表现出超过2.4倍的增强的甲醇电氧化活性，以及​​期望的稳定性和显着改善的CO耐受性。这些改善不仅归因于被PG中引入的缺陷锚定的均匀分散的Pt纳米颗粒，而且归因于Pt和PG之间的强相互作用导致负d波段中心偏移和CO在Pt上的吸附减弱。因此，PG是用于Pt基催化剂实现甲醇电氧化的有前途的载体材料。
