The sustainable transformation of basic chemicals into organic compounds of industrial interest using mild oxidation processes has proved to be challenging. The production of cyclohexanol and cyclohexanone from cyclohexane is of interest to the nylon manufacturing industry. However, the industrial oxidation of cyclohexane is inefficient. Heterogeneous photocatalysis represents an alternative way to synthesize these products, but the optimization of this process is difficult. In this work, the yields of photocatalytic cyclohexane conversion using Degussa P-25 under visible light were optimized. To improve cyclohexanol production, acetonitrile was used as an inert photocatalytic solvent. Experiments showed that the use of the optimized conditions under solar light radiation did not affect the cyclohexanol/cyclohexanone ratio. In addition, the main radical intermediary produced in the reaction was detected by the electronic paramagnetic resonance technique.

Photocatalytic Processes

The application of photocatalytic processes in environmental protection has a short history and is still in its beginnings. This issue, however, provokes continuous interest of the scientific and professional world. This chapter gives the overview of scientific and expert literature related to the application of heterogeneous photocatalysis in tackling the issues related to air protection. The focus is on purification of the indoor air, which comes to abatement of various volatile organic compounds. Basic principles of photocatalytic degradation of gaseous contaminants are presented, mostly on the TiO2 photocatalyst, as well as a detailed account of the effect of various process variables on the rate of the photocatalytic reaction. The problem of TiO2 deactivation is pointed out and deactivation mechanisms are described on the selected reaction system. The chapter aims to review technical aspects of heterogeneous catalysis applied in air protection and special attention is paid to different designs of photoreactors.
