Photoelectrochemical Water Splitting Over Decahedron Shaped BiVO4 Photoanode by Tuning the Experimental Parameters

The present work focusses on the synthesis of structure based BiVO4 Nano particles by hydrothermal method along with a study on experimental result of the structure of the particles in the order of Nano scale to find which is suitable to photo electrode material parameters. The material is further characterised by XRD, FE-SEM, Raman, FT-IR, PL, and UV-Vis DRS along with photo electrochemical water splitting. The various crystal planes of BiVO4 were studied based on XRD and the morphological identification is obtained from FE-SEM. The unique vibrational band spectrum is arrived for the above synthesised material in the range of vibrational band 125 and 208 cm(-1) by Raman. The electro chemical water splitting experiment is carried out for calculating the efficiency of photo generated e(-)/h(+) pair of the BiVO4 material with various pH conditions. Photo electrochemical impedance spectroscopy is also measured based on the above preparation and the characterisation of the material proves to have the potential for photoelectrohemical applications.
