Abstract

The invention belongs to the technical field of preparation of environmental functional materials, and relates to the preparation and application of a self-heating multi-stage sulfide in-situ grown black sponge driven by solar energy; the steps are as follows: dissolving tungsten hexachloride and thioacetamide in deionized Stir in water to obtain a colorless and clear solution; after the waste rubber sponge is properly cut, it is immersed in the solution and transferred to the reaction kettle for hydrothermal reaction. After the reaction, the waste rubber sponge is taken out and washed with absolute ethanol, and a black block is obtained after drying ; Disperse ammonium molybdate and thiourea in deionized water, stir to form a colorless and transparent solution; immerse the black block and transfer it to a reaction kettle for hydrothermal reaction. After the reaction, take out the product and wash it with absolute ethanol and ionized water , freeze-drying to obtain a black sponge with multi-level sulfide growth in situ. The material prepared by the invention has super-hydrophobic and super-oleophilic ability, relatively high strength and thermal stability, can stably absorb light and heat itself under sunlight conditions, and can absorb heavy oil with high viscosity.

Description

technical field [0001] The invention belongs to the technical field of preparation of environmental functional materials, and in particular relates to the preparation and application of a self-heating multi-stage sulfide in-situ grown black sponge driven by solar energy. Background technique [0002] Nowadays, human beings rely more and more on crude oil and its accessories. According to statistics, crude oil production has reached 30.7 million barrels per day in 2019, and this figure continues to grow. With the large-scale oil extraction, the frequency of oil spill accidents is higher than before. Leakage not only wastes precious resources and causes huge economic losses, but also causes serious damage to the marine ecological environment. Common oil-water separation methods include oil grid method, combustion method, chemical degradation method and microbial method, but they are often accompanied by problems such as low separation efficiency, high economic cost and secon...
