Problems solved by technology

However, the photocatalytic activity of nano-tin disulfide is restricted by factors such as the high recombination rate of photogenerated electrons and holes, the low utilization rate of visible light, and the ease of agglomeration. Therefore, how to improve its photocatalytic activity is a common concern.

Embodiment 1

[0023] Preparation of loofah pulp: Soak 2 grams of natural loofah pulp in acetone and absolute ethanol for ultrasonic vibration, then soak the loofah pulp in tin tetrachloride solution for 10 minutes, and then put it in an oven at 110 degrees Celsius for 20 minutes.

[0024] Preparation of tin disulfide: 2 grams of tin tetrachloride, 1.5 grams of thioacetamide and 400 milliliters of absolute ethanol were mixed evenly, and put into an oven at 160 degrees Celsius to react for 12 hours to obtain a solid-liquid mixture. Wash twice successively with 100 milliliters of distilled water and 100 milliliters of absolute ethanol, and the solid is taken out with ethanol, and dried in vacuum at 60 degrees Celsius for 24 hours.

Embodiment 2

[0026] Soak 2.2 grams of natural loofah pulp in acetone and absolute ethanol in turn for ultrasonic vibration, then soak the loofah pulp in tin tetrachloride solution for 12 minutes, and then put it in an oven at 110 degrees Celsius for 22 minutes. Subsequently the sponge gourd pulp of drying, 3 grams of tin tetrachloride, 1.8 grams of thioacetamide and 400 milliliters of dehydrated alcohol are mixed homogeneously, put into 160 degree centigrade baking oven and react 12 hours, obtain solid-liquid mixture. Washed twice with 100 ml of distilled water and 100 ml of absolute ethanol in turn, the solid was taken out with ethanol, and dried in vacuum at 60 degrees Celsius for 24 hours.

Embodiment 3

[0028] Soak 2.4 grams of natural loofah pulp in acetone and absolute ethanol in turn for ultrasonic vibration, then soak the loofah pulp in tin tetrachloride solution for 14 minutes, and then put it in an oven at 110 degrees Celsius for 24 minutes. Subsequently, the loofah pulp of drying, 4 grams of tin tetrachloride, 2.1 grams of thioacetamide and 100 milliliters of dehydrated alcohol were mixed homogeneously, and were put into an oven at 160 degrees Celsius to react for 12 hours to obtain a solid-liquid mixture. Washed twice with 100 ml of distilled water and 100 ml of absolute ethanol in turn, the solid was taken out with ethanol, and dried in vacuum at 60 degrees Celsius for 24 hours.

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...
