Production of hydrogen from photocatalytic water splitting holds promise as an alternative energy source with superiority of cleanliness, environment friendliness, low price, and sustainability. Perfectly constructing the noble-metal-free and stable hybrid structure photocatalyst is quite essential; herein, for the first time the authors aim to use cobalt phosphide as the cocatalyst on titanium oxide to form a novel hybrid structure to enhance the utilization of the photoexcited electrons in redox reactions for improved photocatalytic H-2 evolution activity. Thus, the achieved significantly increased photocatalytic H-2-evolution rate on the optimized CoP/TiO2 (8350 mu mol h(-1) g(-1)) is 11 times higher than that of the pristine TiO2. Moreover, this work is expected to spur more insight into synthesizing such novel photofunctional systems, achieving high photocatalytic H-2 evolution activity and sufficient stability for solar-to-chemical conversion and utilization.
