Photocatalytic processes utilizing the energy of light quanta to synthesize valuable compounds are studied quite widely, but particular attention is paid to the development of effective and stable photocatalysts. The present study considers the transformation of photocatalysts based on TiO2 modified with copper and its oxide compounds (CuOx) in the conditions of CO2 reduction under the LED irradiation (397 nm). The influence of TiO2 precalcination on the state of the copper cocatalyst is demonstrated. It is shown by in situ X-ray absorption (XANES) that modifying the calcined TiO2 photocatalyst with copper results in higher content of (0) and (1+) copper sates than in the case of the non-calcined photocatalyst. It is established that the fraction of metal copper in both photocatalysts increases during the reaction due to the accumulation of photogenerated electrons on the copper cocatalyst.
