A Review on Photo catalysis for Air Treatment: From Catalyst Development to Reactor Design

Abstract

The intriguing possibilities in environmental remediation, chemical synthesis, and energy innovation have prompted significant research into photo catalysis for many decades. However, photo catalysis' functional uses in the area of building materials have been limited. Solving the problems of poor quantum efficiency in solar energy conversion and low levels of contaminants in photo degradation is very challenging. Photocatalytic oxidation of different pollutants, such as volatile organic chemicals or inorganic gases at relatively low concentrations, seems to be more commercially viable for air cleaning. This study begins with an introduction to PCO's contaminant removal process, followed by a thorough examination and discussion of photo catalysts and reactor architecture. This article intends to provide basic and detailed data for paving the way for commercialized gas-phase photo degradation.
