Background
The solar energy is a focus of great attention on photolysis water hydrogen production, and the photocatalytic hydrogen production is a technology capable of converting solar energy into clean and renewable hydrogen energy. Compared with single metal sulfide, the bimetal sulfide shows obvious advantages in the process of photocatalytic hydrogen production by virtue of unique bimetal synergistic effect.
The Polyacids (POMs) are used as a molecular platform capable of providing a plurality of transition metal sources at the same time, and the problem that the growth process is difficult to control due to inconsistent nucleation rates of all components caused by the introduction of the transition metals is well solved. In particular, in one aspect, the polyoxometallate, as a polynuclear inorganic metal anionic oxygen cluster, can provide multiple sources of early transition metals (particularly Mo)VI、WVIAnd VV). Another one isIn one aspect, the organometallic polymer has a diverse, tunable structure that facilitates the introduction of a second transition metal (particularly Co, Ni, Fe, Mn, etc.). Thus, the polyacid-based metal-organic coordination polymers as precursors provide opportunities for the synthesis of highly dispersed bimetallic sulfide materials.

And (3) after the solution is cooled to room temperature, carrying out suction filtration and washing to obtain gray powder, namely the nickel-molybdenum nonapolyacid, and drying in a 60 ℃ oven for later use.
(2) Weighing 0.0369g of nickel-molybdenum nonapolyacid and 0.06g of thiourea, dispersing in 10ml of deionized water, stirring for 2-3 hours on a magnetic stirrer, placing in a hydrothermal reaction kettle under the reaction conditions of 200 ℃ and 24 hours, and naturally cooling to room temperature after the reaction is finished.
(3) Repeatedly washing the obtained composite material with deionized water, and drying in a 60 ℃ oven to obtain Ni3S2-MoS2And forming flower-like clusters.
The application of the nickel metal sulfide derived from polymolybdic acid is mainly in the aspect of hydrogen production by photocatalytic water.
The application method comprises the following steps: sodium sulfide and anhydrous sodium sulfite are used as sacrificial agents, a system for producing hydrogen by photocatalytic water decomposition is used as a catalytic system with the highest hydrogen production, and the average hydrogen production efficiency is 2770 mu mol g-1·h-1Therefore, the polymolybdic acid-derived nickel metal sulfide is a high-efficiency photocatalyst for photocatalytic water decomposition.
Compared with the prior art, the invention has the following characteristics:
the invention adopts Polyacid (POMs) as a molecular platform which can provide a plurality of transition metal sources at the same time, and well solves the problem that the growth process is difficult to control due to the inconsistent nucleation rate of each component caused by the introduction of the transition metal.
