Preparation and modification of copper bismuth-ate photo catalysts and their application in the field of energy and environmental protection

以具有成本低、光催化降解效果好、无二次污染等优点的铋酸铜光催化剂为研究基础,从形貌调控、元素掺杂、贵金属沉积、半导体复合以及碳材料复合等方面介绍铋酸铜的制备与改性。改性后的铋酸铜光催化剂不仅能有效拓宽光响应范围、抑制光生载流子的复合、提高光催化活性,还可以增加材料的稳定性,在治理有害废气、水中污染物以及产氢、产过氧化氢等能源环保领域中表现出优异的性能,为铋酸铜光催化剂在能源环保领域的开发利用提供了参考价值。

Based on the research of copper bismuth-ate photo catalysts with low cost,good photo catalytic degradation effect and no secondary pollution,this paper introduces the preparation and modification of copper bismuth from the aspects of morphology regulation,element doping,precious metal deposition,semiconductor composite and carbon material composite.The modified copper bismuth-ate photo catalysts can not only effectively broaden the range of photo response,inhibit the recombination of photo generated carriers,improve the photo catalytic activity,but also increase the stability of the material,and show excellent performance in the field of energy and environmental protection such as the treatment of harmful waste gases,water pollutants,hydrogen production,hydrogen peroxide production,etc.,which provides reference value for the development and utilization of copper bismuth-ate photo catalysts in the field of energy and environmental protection.
