摘　　要：介绍了一些有关抑制Cu_(2)O光腐蚀的最新研究进展。通过改变晶体形貌,发现(110)和(111)面相对于(100)面具有更好的光催化活性;通过控制晶体粒径,表明与纳米粒子相比,微晶Cu_(2)O的稳定性更好;通过构建异质结结构,可以有效地将电子或空穴从Cu_(2)O光催化剂中分离,增强了Cu_(2)O的光稳定性。以上策略的共同点都是改善载流子从Cu_(2)O到反应物或其他催化剂的转移,以避免载流子在颗粒内聚集,从而达到抑制Cu_(2)O光腐蚀的目的。认识与光腐蚀有关的载流子迁移过程及影响因素对于优化Cu_(2)O及复合光催化剂设计以提高性能至关重要。Recent research progresses in the inhibition of Cu_(2)O photo corrosion were introduced.It is found that the(110)and(111)faces of Cu_(2)O crystals have better photocatalytic activity than the(100)faces by adjusting the crystal morphology.Some research show that the stability of microcrystalline Cu_(2)O is better than that of nanoparticles by controlling the crystal size.The excited electrons or holes in Cu_(2)O photocatalyst can be effectively separated by constructing heterojunction structure,which enhances the photostability of Cu_(2)O.The common point of the above strategies is to improve the migration of charge carriers from Cu_(2)O to the reactants or other catalysts,which avoiding the accumulation of charge carries in particlesand inhibiting the photo-corrosion of Cu_(2)O.To understand of the charge carriers migration and its influence factors concerned with Cu_(2)O photo-corrosion is pivotal to optimize the design of Cu_(2)O photocatalyst and then enhance performance in the future.
