Abstract

Initially, this project attempted to demonstrate the purposefulness of the design and construction of the photoreactor by presenting the details of the design of photoreactor components in the form of electrical and mechanical drawings, serving as the foundation for the standardization of operational parameters affecting the performance of photocatalytic materials. In the following, it provides a discussion of the results of analyses pertaining to the characterization of selected photocatalytic materials as representatives of photocatalytic families active under ultraviolet and visible radiation, which, in addition to the prediction of their properties under a variety of operational conditions, establishes a foundation for the scientific justification and rationality of the effectiveness of the photocatalytic performance efficiency of the aforementioned materials in relation to the operating conditions of the photoreactor. In the final part, operating conditions affecting performance efficiency and their range have been discussed and optimized in detail to investigate the performance of photocatalytic materials. This project, by designing and installing new mixing systems, radiation sources, reaction cell holders, and a temperature controller in the photoreactor, investigating the effects of operational parameters controlled by them on photocatalytic performance efficiency, and presenting a report, was able to take a successful step towards the standardization of photocatalytic processes.
