style=\"color:red\">Lin</span>等报道了一个碱性的水溶液中混合Cu(Ⅱ)盐和6,6-dihydroxy-2,2-bipyri-dine(H2L)的高效电催化水氧化催化剂体系.2015年,Sun等在近中性的硼酸缓冲溶液中采用简便的电沉积Cu2+制备了一个高效的铜氧化物电催化水氧化催化剂.然而,基于地球上充足的Cu设计高效、容易制备和稳定的光催化水氧化催化剂,仍是一个巨大的挑战.本文基于地球丰产元素Cu和O,成功合成了花状的三维CuO微球,并采用扫描电镜、透射电镜、红外光谱、X射线粉末衍射、拉曼光谱、X射线光电子能谱、N2吸附脱附等温线对CuO样品的物相、元素组成、颗粒大小以及比表面积等进行了表征.在可见光下,以[Ru(bpy)3]2+为光敏剂,Na2S2O8为牺牲电子受体,首次报道了CuO微球用作水氧化催化剂.通过一系列控制实验证明CuO确实参与了催化过程.据我们所知,这是第一例铜物种在近中性条件下被证明具有光催化水氧化催化性能.通过对缓冲溶液、pH值和催化剂浓度的优化,在硼酸缓冲溶液(pH=8.5)中产生的O2收率为11.5％,CuO显示了最佳的催化活性.进一步研究表明,CuO表现出卓越的水氧化催化性能和稳定性.催化剂重复使用5次后活性基本保持不变.反应前后的催化剂组成和形貌基本没有发生改变,其表面性质也未发生明显变化.18O标记的重氧水实验证明,氧气中的氧确实是来自于水.实验发现,催化剂活性主要取决于其比表面积.结合已报道的文献,我们初步提出了一个光催化水氧化反应机理.相对于钴、镍和钒,铜丰度高,价格更低,具有更好的发展潜力.可见,丰度高、低毒性和合适的氧化还原性质使铜催化剂填补了光催化水分解的一项空白.","authors":[{"authorName":"杜晓强","id":"80c3f151-d841-4b3d-aa18-a72c54cc2254","originalAuthorName":"杜晓强"},{"authorName":"黄静伟","id":"8db3b79e-bce4-4bec-817d-be974d01d1bd","originalAuthorName":"黄静伟"},{"authorName":"丰营营","id":"62d78f98-eb26-4f61-913d-dfda704e3cc9","originalAuthorName":"丰营营"},{"authorName":"丁勇","id":"7a284b0a-8453-4508-ace4-fcbcd244d71e","originalAuthorName":"丁勇"}],"doi":"10.1016/S1872-2067(15)61012-9","fpage":"123","id":"c5aa6265-6169-415b-918c-4f8ec8a57607","issue":"1","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报
