“…However, its agglomeration property reduces its active oxidant utilization and increases the transportation resistance in catalysis process. 3 One or two dimensional graphitized carbon materials, such as carbon nanotubes, graphene have been used as supporting materials with unique electronic and chemical properties. 4,5 For example, Gong et al used oxygen functionalized carbon nanotubes supported NiO/Ni heterostructures for hydrogen generation from water electrolysis.…”
