Abstract: The invention relates to a method for preparing a molecularly imprinted photocatalyst through in-situ hydrothermal synthesis as well as a product and application of the product. The preparation methodcomprises the following steps: uniformly mixing an aluminum salt and a zinc salt, taking anhydrous Na2CO3 as a precipitator, and regulating the pH value of the system to be neutral; dripping more than two nitrobenzene compounds in the equal molar ratio into the mixture to serve as template molecules, transferring a precursor solution into a high-pressure hydrothermal reactor, reacting at a temperature of 150-180 DEG C for 12-24 hours, cleaning and calcining the obtained supported photocatalytic material, and removing the template molecules, thereby obtaining the supported Al-N co-doped ZnO photocatalytic material with target molecular imprinting sites. According to the method disclosed by the invention, the specific molecular recognition ability of a molecular imprinting technology is combined with a nano photocatalytic oxidation technology, advantages of the two technologies are fully achieved, the adsorption capacity and the electronic transmission performance of targeted pollutantsare effectively improved, and selective rapid degradation of low-concentration highly refractory nitrobenzene compounds is realized in a system in which multiple pollutants coexist.
