Abstract	Noble-metal-free CdS@NixCo1-xO photocatalyst were resoundingly synthesized for the first time using metal–organic framework (MOF) to serve as template for efficient visible-light photocatalytic H2 production. The entire preparation process mainly involved with the calcination of NiCo-MOF and subsequent decoration of CdS nanoparticles (NPs) via hydrothermal treatment. The photoelectrical properties of pristine NixCo1-xO are optimized. With the introduction of CdS NPs, the H2 production of CdS@NixCo1-xO under visible light irradiation (λ＞420 nm) increased significantly from 0 to 2795.6 μmol g−1 h−1, thereby indicating the excellent synergistic effect between CdS and NixCo1-xO skeleton. The band gap of CdS in CdS@NixCo1-xO samples can be narrowed to ca. 1.54 eV. Compared with NixCo1-xO, CdS@NixCo1-xO presents an enhanced electron paramagnetic resonance (EPR) peak and low photoluminescence (PL) spectrum, directing proving its excellent charge carriers separation ability. Besides, the large specific surface ar...
