A facile and fast one-step synthesis of Cu-S composites was demonstrated, the confirmed structures including Cu2S, Cu7S4 and CuS. The hybrid structures of Cu2-xS that combining with Pd nanoparticles could also achieve a noticeable enhancement in hydrogen production with highly stability. Not only the changing optical properties could be addressed, but the plasmon enhancement capacity in this system was also used to improve the H2 generation efficiency by photocatalysis. Among samples with different Cu-S compositions, Cu7S4 samples exhibited the highest activity in terms of H2 evolution rate (25.54 mmol/g.h). Moreover, a marked enhancement of the H2 evolution rate (157.04 mmol/g.h) could be achieved after decorating the Cu2-xS nanowires with Pd nanoparticles to form the hybrid structures.
