Abstract
The invention discloses a p-methyl benzoic acid uranyl complex photocatalyst. The molecular formula of the p-methyl benzoic acid uranyl complex photocatalyst is [(UO2)(C2H6SO)(p-CH3-C6H4-COO)2]2, wherein p-CH3-C6H4-COOH in the formula is p-methyl benzoic acid. The p-methyl benzoic acid uranyl complex photocatalyst can degrade dyes and organic pollutants, and the p-methyl benzoic acid uranyl complex photocatalyst can be recycled by a centrifugal separation method, thus, secondary pollution possibly caused by the catalyst is avoided.
Description
Technical field
The present invention relates to photochemical catalyst, be specifically related to a kind of p-methylbenzoic acid Complexes of Uranyl photochemical catalyst.
Background technology
Along with the development of industrial process, people's living standard has obtained increasing substantially, but the environment of meanwhile also depending on for existence to people has brought destructive influences.Annual all can have a large amount of dyestuffs, hormone, residues of banned pesticides etc. to have the harmful substance of great threat constantly to enter rivers,lakes and seas to our health, and these harmful substances have brought great impact to biological existence.How low energy consumption, low cost, the noxious materials such as dyestuff in dynamical removal industrial wastewater have become the focus that people pay close attention to, and use photochemical catalyst to solve this problem, are undoubtedly best selection.Because photocatalysis technology has, can directly utilize solar energy to solve the potential application of the problems such as the exhaustion of the energy and earth environment pollution, thereby the preparation of photochemical catalyst has caused people's very big interest.The environmental pollution problem, various countries environmental science worker has carried out extensive and deep exploration in this field of photocatalysis, has obtained many gratifying achievements, and has obtained application aspect environmental protection.Especially photocatalysis technology can be CO by the many organic pollutant degradations in water
2and H
2the simple inorganic matter such as O, have that energy consumption is low, easy and simple to handle, reaction condition is gentle, the advantages such as the recyclable recycling non-secondary pollution of catalyst and decomposition rate are fast, become new energy-efficient environmental pollution treatment technology, application for a patent for invention as publication number is CN1618518, disclose with TiO
2with the composite photo-catalyst that ZnO is raw material, can be used for curbing environmental pollution.For this problem, the present invention develops the Complexes of Uranyl photochemical catalyst that a kind of Photocatalytic Degradation Property is good.
Summary of the invention
