Abstract

The development, and demonstration of efficiencies, of photocatalytic technologies are often dependent on the method by which activity is measured. The screening of both materials and reactors is a key aspect in the development process and both are critical in determining whether the technology is suitable for a required application. Given this, detection and quantification of radical species produced during photocatalysis have become an area of increasing interest. As a result, several direct and indirect methods have been developed to measure reactive oxygen species such as O₂^•-, ^•OH, and H₂O₂. This chapter explores these approaches including their advantages, limitations, and whether they are accurate as a representation of photocatalytic activity.
