[0025] Step 1: Preparation of MoS by hydrothermal method 2 . 0.010mol of sodium molybdate (Na 2 MoO 4 2H 2 O) Dissolve in 30.0 mL deionized water and ultrasonically disperse for 30 minutes. Then 0.040mol thiourea [(NH 2 ) 2 CS] was dissolved in 30.0 mL of deionized water, and also ultrasonically dispersed for 30 minutes. The thiourea aqueous solution was slowly added dropwise into the sodium molybdate aqueous solution under magnetic stirring, and stirred for 1 h to make it evenly mixed. Then the mixed solution was transferred to a 100 mL hydrothermal autoclave, and placed in a blast oven at 200 °C for 24 h. After the reaction is complete, cool to room temperature, vacuum filter, wash with deionized water and ethanol until neutral, and remove soluble matter. Finally, the final product was dried in a vacuum oven at 60°C for 6 hours to obtain MoS 2 sample.

Abstract

The invention discloses a preparation method of a catalytic hydrogen production material, the catalytic hydrogen production material and application. The preparation method comprises the following steps: A, preparing a 2H-MoS2 matrix; and B, placing the 2H-MoS2 matrix in a solution containing a heteromonatomic salt, and uniformly dispersing heteromonatoms on the surface of the 2H-MoS2 matrix in a monatomic form through heat exchange reaction, wherein the heteromonatoms are any one of manganese atoms and iron atoms. According to the electro-catalytic hydrogen production material obtained by the invention, the monatom has high dispersity and high stability, the whole electro-catalytic hydrogen production material also has high hydrogen evolution activity, and a technical scheme with low price is provided for replacing a noble metal Pt catalyst.

Description

technical field [0001] The invention relates to new energy technology, in particular to a preparation method of a catalytic hydrogen production material, a catalytic hydrogen production material and its application. Background technique [0002] Hydrogen energy is considered to be the ultimate substitute for fossil energy and one of the best ways to achieve carbon peaking and carbon neutrality. As a carrier of energy, hydrogen is mainly derived from "grey hydrogen", "blue hydrogen" and "green hydrogen" pathways. Using photovoltaic power generation, wind power generation and hydropower generation to electrolyze water to produce hydrogen can fundamentally achieve carbon peaking and carbon neutrality. However, the noble metal platinum electrode used for electrolysis of water to produce hydrogen is limited by its high cost. To this end, non-noble metal hydrogen evolution electrocatalysts have been developed. Molybdenum sulfide (MoS 2 ) has attracted much attention because of...
