Designing and fabricating an efficient and reusable photocatalyst has become a pursuit, as photocatalyst plays a key role in solving the energy crisis and the environmental pollution. However, the major stumbling blocks such as low photo-efficiency, non-reusability and serious electron–hole recombination hinder practical application of photocatalyst. Herein, a novel self-growing ZnO with numerous nanosheets grown on the surface of dumbbell-shape have been successfully synthesized via a simple hydrothermal growth, meanwhile, the nanosheet was e...
