Description Hydrogenation of oxides such as TiO2 is so far considered as a time consuming and complex process which requires high temperature annealing in hydrogen atmosphere. In this work, an electrochemical method for the hydrogenation of metal oxides is introduced. The electrochemical hydrogenation process is a low cost process which requires only a few seconds for synthesizing the black semiconducting oxides. Water with small amount (0.2 vol%) of ionic species like fluorine ions is used as electrolyte. The black semiconducting oxides prepared using the electrochemical hydrogenation process exhibit very good absorption of light in visible region. (C) 2014 Elsevier B.V. All rights reserved.
