摘要

A novel high-efficiency photoelectrode (Fe2O3/reduced graphene oxide/CdS) built from heterostructure and conductive scaffold has been successfully designed and synthesized. Reduced graphene oxide works as a "bridge" which benefits for electron and hole transport. The obtained heterostructure photoelectrodes were systematically characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The photoconversion efficiency (eta) and photocurrent densities vs. time (I-t) curves responding to monochromatic lights have been further investigated in-depth, which reveals that introduction of CdS and reduced graphene oxide played an important role in the enhancement of photoelectrochemical performance.
