Synthesis and application of novel photocatalyst 1-(aminomethyl) cyclohexyl acetic acid salicylaldehyde Schiff base-copper (II) microcrystal

Abstract

The invention belongs to a photocatalyst in the field of environmental water pollution treatment and a preparation method thereof, and the preparation method comprises the following steps: dissolving hydrochloric acid acidified 1-(aminomethyl) cyclohexyl acetic acid in absolute ethyl alcohol, dropwise adding an absolute ethyl alcohol solution of salicylaldehyde under a heating condition, and continuing to react after adding, recrystallizing an obtained yellow precipitate with absolute ethyl alcohol to obtain an intermediate product 1-(aminomethyl) cyclohexyl acetic acid salicylaldehyde Schiff base; dissolving the intermediate product in absolute methanol, adding CuCl2. 2H2O for reaction, filtering to remove insoluble substances, slowly volatilizing filtrate in a magnetic field and a dust-free environment for a plurality of days, and separating out green needle-like microcrystals from the solution, and filtering and collecting green needle-like microcrystals, washing with methanol, and drying to obtain the 1-(aminomethyl) cyclohexyl acetic acid salicylaldehyde Schiff base-copper (II) complex microcrystals. Photocatalysis experiments show that the prepared copper (II) complex microcrystal has good catalytic degradation activity on various organic pollutants in water.

Description

technical field [0001] The invention belongs to the treatment of environmental water pollution, and in particular relates to a catalyst and a preparation method for catalytically degrading complex organic pollutants in water under the irradiation of visible light. [0002] technical background [0003] Water pollution is an important factor restricting the development of industry and agriculture, leading to an increase in industrial production costs and a decline in the quality of agricultural products. In addition, water pollution also has adverse effects on the health of residents, which has become an urgent problem to be solved in the construction of ecological civilization. Solving the problem of water pollution has become an environmental problem that our country and even countries in the world are currently facing. Organic pollutants in water come from a wide range of sources, complex components, and are generally toxic. It is difficult for traditional sewage treatment...

Problems solved by technology

Metal oxide semiconductor materials such as titanium dioxide and zinc oxide are the first type of photocatalysts that have been paid attention to, but these catalysts have the disadvantages of low light energy utilization and easy recombination of photogenerated electrons and holes, which are limited in practical applications.
