Layered double hydroxide (LDH)-based photocatalysts have attracted more attention in photocatalysis due to their low cost, wide band gaps, and adjustable photocatalytic active sites; however, photogenerated carrier separation efficiency limits efficiency. Herein, a NiAl-LDH/Ni-doped Zn0.5Cd0.5S (LDH/Ni-ZCS) S-scheme heterojunction is rationally designed constructed from kinetically thermodynamically favorable angles. The 15% LDH/1% Ni-ZCS displays comparable hydrogen evolution (PHE) activity with rate of 6584.0 μmol g-1 h-1, which exceeds by ∼6.14- ∼1.73-fold those ZCS 1% Ni-ZCS, respectively, outperforms most the previously reported LDH-based metal sulfide-based photocatalysts. In addition, apparent quantum yield reaches 12.1% at 420 nm. situ X-ray photoelectron spectroscopy, photodeposition, theoretical calculation reveal specific transfer path carriers. On this basis, we propose possible mechanism. fabrication not only accelerates carriers but also decreases activation energy H2 improves redox capacity. Moreover, there are huge amounts hydroxyl groups distributed on surface photocatalysts, highly polar easy combine H2O large dielectric constant form bond, can further accelerate PHE.
