Effective Visible Light Exploitation by Copper Molybdo-tungstate Photoanodes.

ABSTRACT: The need for stable oxide-based semiconductors with a narrow band gap, able to maximize the exploitation of the visible light portion of the solar spectrum, is a challenging issue for photoelectrocatalytic (PEC) applications. In the present work, CuW_1-x Mo _x O₄ (E _g = 2.0 eV for x = 0.5), which exhibits a significantly reduced optical band gap E _g compared with isostructural CuWO₄ (E _g = 2.3 eV), was investigated as a photoactive material for the preparation of photoanodes. CuW_0.5Mo_0.5O₄ electrodes with different thicknesses (80-530 nm), prepared by a simple solution-based process in the form of multilayer films, effectively exhibit visible
