Preparation of Photoresponse n-TiO2 for hydrogen and oxygen evolution reactions in an electrochemical cell

Abstract

Today, energy crisis triggered by depletion and pollution aspect of fossil fuels, has urged the need to search of clean and renewable energy, which can effectively substitute petroleum. The use of hydrogen as an environmentally friendly fuel had been encouraged since the combustion of hydrogen results in the generation of water, which neither results in air pollution nor leads to the emission of greenhouse gases. A sol-gel method with powder methodology processing has been implemented in this experiment to prepare for the BST, BaxSr1-xTiO3 bulk film to evaluate the solar hydrogen energy generating in photo-electrochemical cell (PEC). The structure and morphology are the main factor in concern. Results showed that composition of Ba0.4Sr0.6TiO3 and Ba0.6Sr0.4TiO3 are good composition in generating the photo-voltage of solar hydrogen.
