Graphical abstract
Firstly, uniform solid MF resin spheres were synthesized by polycondensation using PVA as dispersant and blended with GO to produce MF/GO composite after ultrasonic treatment. MF resin spheres were assembled into the GO sheets in the process of mixing. Secondly, HMCS/GN composite was obtained after the pyrolysis of the MF/GO composite under Ar gas protection. PVA and carbonization temperature play an important role in controlling the hollow structure of the MF resin spheres in the second process. | Simultaneous Pt deposition and nitrogen doping of graphene as efficient and durable electrocatalysts for methanol oxidation Original Research Article

Graphical abstractIn this work, we described a facile one-pot reaction for the simultaneous reduction of graphene oxide to graphene, nitrogen doping of graphene with urea, and deposition of Pt nanoparticles on doped graphene to prepare N-doped graphene supported Pt nano-electrocatalysts (Pt/N-graphene) for methanol oxidation. Compared with the updoped Pt/graphene catalyst, Pt/N-graphene presented excellent activity and durability towards methanol oxidation reaction contributed nitrogen doping.
