Bimetallic nitrides Co3Mo3N nanosheets combined with phosphorus-doped carbon as superior Pt-based catalyst carriers for methanol electrooxidation reaction

Facile constructing novel and stable carrier of Pt-based catalyst for excellent methanol electrochemical is profitable. To this end, a clean and simple synthetic route is used to synthesize Pt supported by bimetallic nitride Co 3 Mo 3 N catalysts (Pt/Co–Co 3 Mo 3 N/PC). On the one hand, thanks to the intensive interaction between Co 3 Mo 3 N and Pt NPs and the ability of Co 3 Mo 3 N itself to provide adsorption OH by decomposing water; on the other hand, P-doped carbon brings an increase in defect sites for better anchoring of Pt NPs, the catalyst Pt/Co–Co 3 Mo 3 N/PC possesses excellent improved catalytic performance for methanol electrooxidation , in which the mass activity is 910 ​mA‧mg −1 Pt , which is about 2.1 times that of Pt/C-JM. Additionally, the specific activity, anti-CO poisoning capability, and long-term stability of the catalyst are far outstanding to those of Pt/C-JM. The experimental approach in this paper also provides ideas for the commercial application of Pt-based catalysts.
