Cu<inf>2</inf>O octahedrons, rhombic dodecahedrons and cubes were prepared and evaluated for the reduction of hexavalent chromium under visible light irradiation. The specific activity of Cu<inf>2</inf>O with different crystal planes followed the order {111} >{110} >{100}. The surface capping ligands of octahedral and rhombic dodecahedral Cu<inf>2</inf>O have no blocking effect on their photocatalytic performance. ©2015 Dalian Institute of Chemical Physics, the Chinese Academy of Science...

Cr(VI)具有高毒性和强诱变致癌性,且能稳定存在于自然界中,对人类和自然环境危害极大.而容易沉淀和吸附在固体上的Cr(III)毒性较小,约为Cr(VI)的千分之一.因此,将Cr(VI)还原为Cr(III)是处理含铬废水的有效途径.光催化还原是一种环境友好的新型技术,基于可见光的催化还原处理含Cr(VI)废水能够在常温常压下进行,具有经济、高效、清洁和无二次污染等特点而受到广泛关注.采用适宜的晶面生长控制剂,调变不同晶面的相对生长速率,可制得暴露不同晶面、具有多种形貌的Cu2O.将这些具有不同晶面的Cu2O用于光催化氧化降解有机污染物的研究表明, Cu2O的光催化氧化性能与其所暴露的晶面密切相关,其表面残留的...
