摘要
Alcohol fuels oxidation plays a significant role in carbon sustainable cycling and high-performance cata-lyst with a strong anti-poisoning effect is desired.Herein,Pt-Ni alloy supported on the N-doped graphene aerogel synthesized by simple freeze-drying and annealing was demonstrated to have such catalytic abil-ity for alcohol fuel oxidation.Pt-Ni alloy particles were found uniformly dispersed over the surface of 3D N-doped graphene aerogel.High anti-poisoning ability for CO-like intermediates oxidation was demon-strated by the CO-stripping experiment.The as-prepared catalyst was found to have outstanding catalytic performance for methanol and ethanol oxidation with high catalytic activity,stability and catalytic ki-netics.Compared to the control samples,the improved catalytic ability could be due to the presence of oxophilic Ni species and the support effect of 3D N-doped graphene aerogel that combined multi-advantages of large surface area,facile mass transfer,and abundant defects.
