Abstract

The invention discloses a preparation method for indium trisulfide@graphene oxide nanocomposite. The key technique of the preparation method is that the graphene oxide is adopted as a carrier, the indium trisulfide is adopted as a photocatalyst, and reaction at room temperature is performed to obtain a target object. The preparation method has the following advantages: (1), the preparation methodfor indium trisulfide@graphene oxide nanocomposite is simple and feasible, the technological parameters are easy to control, the indium trisulfide nanocomposite is prepared through a hydro-thermal synthesis method, the energy consumption is low, and the production cost is effectively reduced; (2) the indium trisulfide nanocomposite fully combines the excellent photocatalysis of nano-indium trisulfide, strong load and wrapping capacity of graphene oxide with the photo-induced electron-hole resistance; so that the concerted catalysis effect is excellent.(3), trisulfide nanocomposite in a neutraland acid environment adopts a visible light as a light source, can be used for treating pollutants at large scale, and is high in degradation activity, after the degradation reaction is completed, the catalyst cannot go away, and can well recycled and reused; (4),trisulfide adopts amidos to be sensitized, and the sensitized trisulfide is then compounded with the graphene oxide, instead of being compounded by a one-step hydrothermal method, the adsorption performance of the trisulfide nanocomposite is protected as damage of the one-step hydrothermal method to the oxygen-containing functional groups on the graphene oxide is avoided.

Description

A technical field [0001] The invention relates to the field of nanocomposite materials, in particular to a preparation method of diindium trisulfide@graphene oxide nanocomposite material. Two background technology [0002] Industrial wastewater containing rhodamine B is harmful to humans and animals, and its wastewater treatment process has become a research hotspot in the field of water treatment (Mustafa S, Yunus E U, Erkan Y et al Determination of rhodamine Bin soft drink, waste water and lipstick samples after solidphase extraction. [J]. Food and Chemical Toxicology, 2011, 49: 1796-1799) Due to their remarkable visible light absorption and high energy conversion efficiency, sulfide semiconductor-based photocatalysts have attracted a lot of attention (Fan L, Guoping C , JianghengL et al.Band engineering of Cu 2+ doped in 2x Zn 3(1-x) S 3 solid solution with high photocatalytic activity for H 2 production under visible light. [J]. Catalysis Science & Technology, 201...
