Abstract

Structured potassium titanate (K2Ti8O17, KTO) was synthesized by simple hydrothermal route and CdSe quantum dots (QDs) was synthesized by hot injection method. Further, CdSe QDs were sensitized or modified over synthesized KTO nanorods. The synthesized KTO and CdSe KTO nanorods were subjected to various characterizations techniques such as XRD, FESEM, TEM, UV-visible and FTIR analysis to confirm the particles and its behaviour. The KTO and CdSe KTO electrodes were prepared and investigated as photoanodes in photoelectrochemical water splitting. Photoelectrochemical water splitting action of KTO and CdSe KTO compounds was analyzed in 1 M Na2S electrolyte. The CdSe KTO photoanode demonstrated advanced photoelectrochemical water splitting activity.
