Composition-Dependent Functionality of Copper Vanadate Photoanodes [PDF]
ACS Applied Materials & Interfaces, 2018 To understand functional roles of constituent elements in ternary metal oxide photoanodes, essential photoelectrochemical (PEC) properties are systematically analyzed on a series of copper vanadate compounds with different Cu:V elemental ratios. Homogeneous and highly continuous thin films of β-Cu2V2O7, γ-Cu3V2O8, Cu11V6O26, and Cu5V2O10 are grown via ...

An n-Si/n-Fe2O3 Heterojunction Tandem Photoanode for Solar Water Splitting
CHIMIA, 2013 Few metal oxide photoanodes are able to reduce protons to hydrogen because their conduction band minimum is located at too positive potentials. This can be remedied by biasing the photoanode with a photovoltaic cell placed behind the photoanode.
