In this work, a novel polyoxometalate template-based strategy was applied to construct the bi-metal-doped CdS photocatalysts. NiMo6 polyoxometalate template precursor was applied for the preparation of Ni, Mo co-doped CdS photocatalysts (NiMo-CdS). The structures of the materials were explored by XRD, SEM, HRTEM, HAADF, element mapping, XPS, Raman spectrum and UV-vis DRS. Moreover, the results of the UV-vis spectrum showed that NiMo-CdS exhibited an enhanced performance on light absorption. The results of photocatalytic hydrogen evolution from water splitting demonstrated that the NiMo-CdS showed higher efficiency on hydrogen evolution than noble-metal Pt-doped CdS. The reason could be ascribed to the enhanced light absorption ability and charge separation after Ni and Mo were introduced, which could also act as co-catalysts. The apparent quantum yield (AQY) efficiency could reach 42% at 365 nm. This work proposed a novel and inexpensive method to synthesize the bi-metal (Ni, Mo) decorated CdS photocatalysts for efficient hydrogen evolution from water splitting.

“…The NiO, NiO x, or Ni(OH) 2 materials that can be incorporated with TiO 2 , CdS, SrTiO 3 , and NaTaO 3 are quite common cocatalysts, [67][68][69][70][71][72][73][74][75] which present a great potential to replace noble metals. Nickel oxides and hydroxides are more convenience to be prepared via some facile methods, or controlled their formation, structure, size, and morphology in comparison to other Ni-based compounds.…”

Summary Up to now, much effort has focused on developing the highly efficiency composite photocatalysts by introducing cocatalysts in the photocatalytic hydrogen production reaction, because the proper cocatalysts can reduce activation energy, provide active sites, and suppress the reverse reaction. The transition metal nickel and its compounds acting as cocatalyst have received intensive attention because of their structural stability, facile preparation, and high performance in hydrogen evolution reaction, and are expected to replace the function of noble metals. This review emphasizes on the latest progresses that design and construction of composite photocatalyst using Ni‐based cocatalyst for enhanced hydrogen production, such as metal nickel, nickel sulfide, and nickel phosphide, will be presented. Then, some preparation strategies and influence factors of Ni‐based cocatalysts on enhanced photocatalytic hydrogen production are elucidated in detail. Finally, some challenge and perspective on the highly active cocatalysts in the area of photocatalytic hydrogen production from water splitting are also given.
