Designing a hybrid photocatalyst with multichannel charge separation could address the issue of rapid recombination of photo-induced electron–hole pairs from a single semiconductor and assist photocatalytic hydrogen evolution. In this work, the Ni(OH)2-TiO2-Cu2O ternary hybrid has been successfully prepared with a combination of hydrothermal-calcination-chemical reduction methods. Particularly, Ni(OH)2species and Cu2O nanoparticles are anchored on a TiO2nanoflake assembly. Upon light illumination, photocatalytically splitting water to hydrogen is achieved by the as-synthesized ternary hybrids. Among them, the 0.83% Ni(OH)2-TiO2–4.5% Cu2O hybrid exhibits the highest photocatalytic performance. Particularly, the hydrogen generation rate (8384.84 μmol g–1h –1) of 0.83% Ni(OH)2-TiO2–4.5% Cu2O is 3.5 times higher than that of pristine TiO2(2369.94 μmol g–1h –1). It is also superior to the binary 0.83% Ni(OH)2-TiO2and TiO2–4.5% Cu2O samples. It is demonstrated that the formed p–n junction in the interface of TiO2and Cu2O as well as the cocatalytic effect of Ni(OH)2species could offer multichannels for efficient charge transfer, contributing to the improved photocatalytic hydrogen production.
