Abstract

The invention provides a compound NH4GaS2 and a preparation method and application thereof. The preparation method includes: mixing gallium oxide and thiourea evenly and adding the gallium oxide and thiourea to a reactor; adding oxalic acid and sealing the reactor; heating the reactor for reaction to obtain white granular crystal, namely the compound NH4GaS2, after reaction. The compound NH4GaS2 is synthesized by adopting the simple thiourea oxalate method which is simple and easy to implement, the method does not need to be carried out under harsh vacuum reaction conditions, raw materials arecheap and easy to obtain, and low cost, low energy consumption and easy industrial production are achieved; the compound has good photocatalytic activity for hydrogen production under simulated sunlight and can be used as raw material for the synthesis of other gallium sulfides, and good application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of sulfide preparation, in particular to a compound NH 4 GaS 2 And its preparation method and application. Background technique [0002] Gallium is a scattered metal with low melting point and high boiling point, and has the reputation of "the backbone of the electronics industry". Gallium compounds are high-quality semiconductor materials and are widely used in the optoelectronic industry and microwave communication industry. For example, commonly used semiconductors include gallium nitride, gallium arsenide, and gallium phosphide. Gallium compounds are also used in the manufacture of solar cells, such as gallium arsenide III-V solar cells, which have good heat resistance, radiation resistance and other characteristics, and their photoelectric conversion rate is very high. Initially, because of the high cost of production and use, it was often used in aerospace and military fields. In recent years, the ...
