【摘要】 光催化裂解水产氢和产氧是实现光能转化为化学能的理想路径,而高效产氢及产氧光催化剂的开发则是其核心问题。因此,我们开展了光催化产氧和产氢材料的研究工作。制备了由多孔、超薄类单晶纳米片(<5 nm)组成的空心Co3O4材料[1]。该材料在可见光(>450 nm)下产氧速率达到了~12218μmol g-1 h-1,是同样条件下商业Co3O4的~20倍。我们还制备了一种富锶的多孔SrTiO3材料[2],该材料光催化产氢速率是不含孔SrTiO3纳米粒子产氢速率的3倍,而且持续反应20个循环后,光催化产氢性能仍然保持不变。此外,还获得了一种具有可见光响应的一维多孔CdS/ZnO复合光催化材料,该材料也具有较好的光催化产氢性能[3]。更多还原

【Abstract】 High efficient hydrogen and oxygen evolution catalysts are the key roles for photocatalytic water splitting, which is an idea route for generation of chemical energy by sunlight. Thus, a kind of hollow Co3O4 composed of thin porous nanosheets [1]. Its oxygen evolution rate is ~12218 μmol g-1 h-1, which is about 20 times as that of commercial Co3O4. At the same time, a kind of Sr rich porous Sr TiO 3 was also obtained for hydrogen evolution with high stability [2]. Another porous 1D Cd S/Zn O composite can produce hydrogen efficiently under visible light irradiation [3].更多还原
