Weakening CO poisoning over size-and support-dependent Pt_(n)/X-graphene catalyst(X=C,B,N,n=1-6,13)

摘要

CO poisoning is one of the obstacles for platinum catalysts toward the electro-catalysis process for proton exchange membrane fuel cell(PEMFC)or direct methanol fuel cell(DMFC).Herein,we aim to weaken the CO poisoning on Pt by varying the cluster sizes and supports via doping graphene with B and N based on DFT+D3 calculations.
