Description
技术领域
本发明用以不同铜盐为铜源，通过溶液热沉淀法、微波合成法和高温焙烧法合成微纳结构的CuO，在溶有氧化剂的碱性溶液中，具有良好的催化性能，可与过硫酸盐一起，形成化学氧化水制备氧气的CuO/过硫酸盐氧化剂。
背景技术
当今世界，能源问题和环境问题备受关注。研发新型可持续无污染能源已迫在眉睫。在这些能源中，氢(H2)燃料引起科研工作者的极大兴趣。水的全分解 (2H2O→2H2+O2)引起了科研工作者的极大兴趣。催化水氧化主要为光催化、电催化和化学催化。而化学催化水氧化反应是三者中最方便易行的方法，仅需要催化剂和电子牺牲氧化剂。早期的化学催化水氧化催化剂主要是铱和钌的氧化物，但其高昂的价格限制了它们的商业应用，故研究者将研究对象转向了含量相对丰富且价格较低的过渡金属。近年来，钴、锰、镍、铁等的化合物被证明可以作为化学催化水氧化的催化剂。本发明以不同铜盐为铜源，通过溶液热沉淀法、微波合成法和高温焙烧法合成微纳结构的CuO，在溶有氧化剂的碱性溶液中，具有良好的催化性能，可与过硫酸盐一起，形成化学氧化水制备氧气的CuO/过硫酸盐氧化剂。
