Abstract

Herein, holmium oxide as a support for nanosized Mn oxide was used toward the synthesis of a new catalyst for water oxidation. A composite of Mn and Ho oxide was synthesized by a simple hydrothermal procedure and characterized by scanning electron microscopy, extended edge X-ray absorption fine structure, transmission electron microscopy, powder X-ray diffraction and electrochemical methods. The effect of calcination temperature on the composite performance for the water-oxidation process was examined in the range of 100-600 °C. The turnover frequencies for the catalyst toward water oxidation in the presence of cerium(iv) ammonium nitrate and photo-produced tris(2,2′-bipyridyl)ruthenium(iii), [Ru(bpy)3]3+ are 0.12 and 0.04 (mmol O2 per mol Mn s), respectively. In addition, the catalyst shows self-healing in the presence of cerium(iv) ammonium nitrate and under the water-oxidation conditions.
