Facile synthesis of ZnO nanorods grown on graphene sheets and its enhanced photocatalytic efficiency

摘要

BACKGROUNDRecent advancements in nanoscale materials have focused on well-designed nanocomposites that are highly oriented and organized. Three-dimensional arrays consisting of one-dimensional ZnO nanorods grown on reduced graphene oxide (RGO) sheets should be an efficient photocatalyst for photocatalytic hydrogen production from glycerol solution due to the increased adsorptivity of the reactant, extended light absorption range, and especially efficient charge transportation and separation.
