Highly Dispersed Pt Nanoparticles Doped onto the Surface of Graphene through Aniline Stabilizer

초록

The attachmento f metal nanoparticles(N Ps)t o nanocarbonm aterials,s uch as carbon nanotubes and graphene nanosheets, has received considerable attention with potent iala ppl icat ionsi n sensors,f uel cel ls, bat ter iesa nd catalysts.I n par t icular , graphene has attracted considerable attention in recent years because of its excellent propertiesT. hese remarkablec haracteristicms ake it a promisingc andidatea s a new 2D supportf or loading metal NPs in fuel cell applications.H owever,t he synthesiso f a high-qualityg rapheneimetalN Ps hybridw ith controlleds izesa nd shapes is a great challenge.I n this study, anilinew as used as a stabilizefro r Pt NPs in largeq uantities with a uniform dispersion and small size doped onto the surface of reduced functionalizedg raphene oxide (r-fGO). Consequently,t he catalytic performanceo f the Pt/r-fGO NPs hybrid was enhanced.
