Abstract

The aim of the work is to obtain and characterize a composite photocatalyst based on the spent catalyst of the Shurtan Mining and Chemical Combine based on titanium dioxide and molybdenum-containing waste of the Almalyk Mining and Metallurgical Combine and to identify factors influencing the process of photocatalytic decomposition of methylene blue in solution under the action of UV light. In this work, we studied the kinetics of photocatalytic decomposition of methylene blue on the surface of materials obtained from technogenic solid waste, which were thermally activated at a temperature of 600 ° C. It was found that desorption plays an important role in the decomposition of methylene blue (MB) in solution under UV irradiation, affecting the efficiency and mechanism of the process.
