Embodiment 1

[0029] A kind of CdS / NiPc photocatalyst that can be used for photolysis water, it comprises the steps:

[0030] Step 1: Weigh 4.8mmol of cadmium chloride and 30mmol of sublimed sulfur into a beaker, then add 30mL of diethylenetriamine (DETA) to the beaker and stir for 30min to form a uniform suspension to obtain a cadmium sulfide precursor ;

[0031] Step 2: Add nickel phthalocyanine (NiPc) accounting for 5% of the theoretical mass of cadmium sulfide to the above-mentioned cadmium sulfide precursor solution, and stir for 30 minutes to form a uniform suspension, then transfer the suspension into 50 mL of polytetrafluoroethylene-containing In a stainless steel autoclave with an inner liner, react at 80°C for 48 hours;

[0032] Step 3: The product obtained after the reaction was washed with deionized water and ethanol and centrifuged, and then the solid was transferred to an oven for drying at 70°C for 12 hours to obtain a CdS / NiPc photocatalyst.

Embodiment 2

[0034] The preparation method in this example is the same as that in Example 1, except that the mass of NiPc added in step 2 of this example is 10% of the theoretical mass of CdS, and the rest of the conditions remain unchanged.

Embodiment 3

[0036] The preparation method in this example is the same as that in Example 1, except that the mass of NiPc added in step 2 of this example is 15% of the theoretical mass of CdS, and the rest of the conditions remain unchanged.

Abstract

The invention discloses a CdS / NiPc photocatalyst capable of being used for photolysis of water and a preparation method of the CdS / NiPc photocatalyst, and belongs to the technical field of photocatalysis. According to the invention, cadmium sulfide seeds are formed in a diethylenetriamine (DETA) solvent, different contents of nickel phthalocyanine (NiPc) are added, NiPc is effectively dispersed, the CdS / NiPc photocatalyst is synthesized in situ by using a solvothermal method, and the introduction of NiPc is not only beneficial to widening the response range of visible light, but also beneficial to the separation and transfer of photo-induced charges, thereby improving the photocatalytic activity. The synthesis method is simple in process, easy to operate and low in cost. The prepared CdS / NiPc photocatalyst has excellent performance of hydrogen production by water photolysis.

Description

technical field [0001] The invention belongs to the technical field of photocatalysis, and in particular relates to a CdS / NiPc photocatalyst which can be used for photolysis of water and a preparation method thereof. Background technique [0002] With the rapid development of the world economy, people's overexploitation and utilization of chemical fuels such as petroleum have led to serious environmental and energy crises, which makes the development and utilization of sustainable clean energy to replace fossil fuels the most important challenge facing human society. one of the challenges. As a fuel, hydrogen has the advantages of high energy density, renewability and environmental friendliness, and is considered to be an ideal substitute for fossil energy. Photocatalytic water splitting for hydrogen production is one of the most promising technologies for harvesting hydrogen energy. Currently, various semiconductors are being developed as highly efficient photocatalysts, ...
