摘要: The geometric stability, electronic structure and magnetic properties of the Pt4 clusters on graphene substrates are investigated using first-principles methods. It is found that defective with a single vacancy defect (SV-graphene) have larger binding energies than pristine graphene. different position SV sites can modulate stability clusters. provide more transferred electrons to SV-graphene exhibit positively charged, which helps weaken CO adsorption. results would be important for understanding adsorption behavior metal
