In article number 1400696, Zhongqin Yang, Gengfeng Zheng, and co‐workers report the use of chemically reduced, mesoporous Co 3 O 4 nanowires for enhanced sunlight‐driven water splitting and oxygen evolution reaction. Mesoporous Co 3 O 4 nanowires are effectively reduced by NaBH 4 and new oxygen vacancies are formed during this process. These oxygen vacancies lead to much higher electrical conductivity and electrocatalytic activity of Co 3 O 4 nanowires.
