The Co/G(V) catalysts prepared by the impregnation method were characterized by BET, XRD, H₂-TPR, TEM, XPS, etc., to investigate the effect of different acid vapor pretreatments on their Fischer-Tropsch synthesis performance. The results show that the Co/G(HNO₃) catalyst prepared by pretreating graphene support with nitric acid vapor exhibits the largest specific surface area, pore volume, and pore diameter, higher defect degree, the highest cobalt loading, and optimal catalytic performance.
