The practical application of photocatalytic water splitting is essentially limited by the slow kinetic nature of the water oxidation process. Therefore, it is highly desirable but challenging to explore a low-cost and high-efficiency water oxidation catalyst for the aim of commercialization and industrialization. We herein report the first-time synthesis of a novel and high-efficiency visible-light-driven photocatalyst composed of flower-like Co (CO3)(0.5)(OH)center dot 0.11H(2)O (CCO) nanowires and Bi2WO6 (BWO) nanosheets, i.e. CCO/BWO nanocomposite, via a facile hydrothermal method. Without utilizing any additional cocatalyst, the composite of CCO/ BWO in 30% weight ratio exhibits extraordinarily high photoactivity and photostability towards O-2 evolution, achieving an average O-2 generation rate of 953 mu mol h(-1) g(-1) under visible-light irradiation (lambda > 420 nm).
