▎ 摘　　要

The graphene-derived solids such as doped graphene, graphene oxide (GO), and reduced graphene oxide (rGO) have been identified as supports for preparation of catalysts for various catalytic applications. Among those, hydro processing (HPR) of model compounds as well as feeds from conventional and nonconventional sources has also been evaluated. It was evident that HPR catalysts supported on graphene supports out-performed catalysts supported on other carbon solids. The stability of the former catalysts in the presence of water is of particular importance for the HPR of nonconventional feeds. Graphene solids as supports may play an important role during the development of HPR catalysts not requiring presulfiding. The activity of graphene alone was enhanced either by doping with various dopants or by functionalization. Once active metals were anchored on the surface, the activity of graphene-supported catalysts was increased significantly. Conventional metals such as Mo, Ni, Co, and Fe as well as noble metals such as Pt, Pd, Ru, and Rh have been evaluated as active metals.
