Photoelectrochemical (PEC) water splitting is a promising approach for generating hydrogen from water. In order to enhance PEC water splitting efficiency, it is essential to inhibit the production of the hydrogen peroxide by-product and to reduce the over-potential required, using an inexpensive catalyst and with high current density. We have shown that coating TiO2 electrodes by chiral molecules or chiral films enhances the hydrogen production and reduces the production of H2O2 by-product. The results indicate a new strategy for designing low-cost earth-abundant catalysts where the advantages of the CISS effect are combined with the large effective area provided by the NPs to promote PEC water splitting with high current density. In addition we developed chiral inorganic catalyst, CuO that showed promising results and enables the production of robust system from hydrogen production.
