Abstract

The invention discloses a preparation method of a tin sulfide / vegetable sponge nanocomposite. The technical key lies in that a target product is obtained by carrying out a reaction at high temperatureby taking natural vegetable sponge as a carrier and petal-shaped tin sulfide as a photocatalyst. The preparation method has the advantages that: (1) the vegetable sponge is natural, green, pollution-free, wide in source, cheap and available; (2) the reaction condition is simple, the equipment requirement is low, and the energy consumption is low; (3) the product is good in catalytic effect, highin catalytic efficiency and strong in circularity; and (4) the preparation method is safe and smooth in reaction, free of naked fire or smoke and easy to realize industrial amplification.

Description

A technical field

[0001] The invention relates to the field of nanocomposite materials, in particular to a method for preparing a tin disulfide / loofah nanocomposite material. Two background technology

[0002] Industrial wastewater containing hexavalent chromium ions has become a difficult point in the wastewater treatment process due to its characteristics of large discharge, refractory degradation, and high content of organic matter. Semiconductor photocatalytic technology, as an efficient and green water treatment technology with broad application prospects, has attracted increasing attention (LIU Zi-li, LIU Hong-wei, LI Ru. Photocatalytic reduction of waste water containing Cr(VI) by photocatalyst Cu 2 O[J].J Chem Eng of Chinese Univ, 2007, 21(1):88-92.) (Xu Y H, Liang D H, Liu M L, et al.Preparation and characterization of Cu 2 O-TiO 2 : efficient photocatalytic degradation ofmethyleneblue [J]. Mater Res Bull, 2008, 43(12): 3474-3482.). Among many semiconductor photo...
