Fabrication of a highly efficient and stable nano-modified photoanode for solar H2 generation

Abstract

A highly efficient and stable CdS–TiO₂ nano-modified photoanode (NMP) was achieved by a simple chemical linking method. Both efficiency and stability were enhanced by attaching thioglycerol linked TiO₂ nanoparticles over CdS. The NMP generated twice the photocurrent than an as-made CdS photoanode and displayed a photoelectrochemical stability of minimum 9h of PEC testing.
