析氧反应（OER）仍然是整体水裂解的瓶颈。在此，我们报告了一种新的使用传统的钴掺杂的ZnO纳米棒的带隙为1.77 eV的作为一个无贵金属的光催化剂在可见光照射下的OER。这是CA的出色表现。在可见光照射下（>420 nm），最佳Co掺杂ZnO光催化剂用量为50 mg时，光催化效率可达191.8 μ mol/h。表观量子产率为ca。22.8在420 nm和380 nm波长处，其平均回收率分别为43.5%和43.5%。这项研究表明，这种传统材料有可能使太阳光硬化，以实现有效的水分解和其他先进的光催化应用。
Oxygen evolution reaction (OER) by photocatalysis remains as a bottleneck for overall water splitting. Herein, we report a new use of conventional Co doped ZnO nanorods with a band gap of 1.77 eV as a noble-metal-free photocatalyst for OER under visible light illumination. A remarkable performance of ca. 191.8 mu mol/h is realized by 50 mg of the optimal Co doped ZnO photocatalyst and visible light illumination (>420 nm). The apparent quantum yields are ca. 22.8 % and 43.5 % at the wavelength of 420 nm and 380 nm, respectively. This research suggests the potential of this conventional material to hardness sunlight for efficient water splitting and other advanced photocatalytic applications.
