Fabrication of Amorphous BiOCl/TiO2-C3N4 Heterostructure for Efficient Water Oxidation

摘要

The photo-/electrocatalysis has gained much attention in the recent decades by acquainting variety of catalysts to deal with the energy crises. Keeping in mind the water splitting efficiency of TiO2, we coupled with bismuth oxychlorides (BiOCl) and graphitic carbon nitride (g-C3N4) by low temperature calcina- tion treatment and built an amorphous BiOCl/TiO2-g-C3N4 heterostructure for water oxidation. This material was charac- terized by the state of art spectroscopic and electrochemical techniques such as X-rays diffractions, UV-vis. diffused reflec- tance spectroscopy, scanning electron microscopy, high-reso- lution transmission electron microscopy and photoelectron spectroscopic measurements.
