Abstract

In the future, solar energy, along with other renewable resources, could play a key role in mass productionof fine chemicals. It could also potentially solve environmental problems, as demonstrated by recentdevelopments in the use of solar energy, such as solar photocatalysis. The solar photocatalytic technologyhas been demonstrated to be effective for:• Treating groundwater, drinking water, industrial wastewater, and air and soil pollution,• Water disinfection, and• Industrial production of fine chemicals.This report summarizes the current status of solar photocatalysis and identifies future opportunitiesfor research and industry in this field, including recent relevant bibliography. The main commercial solarphotocatalytic applications are described, included the technologies based on sunlight for antifoggingand self-cleaning of coating materials, glass, and concrete. An overview of several different solar photoreactorsand the main operating process parameters are also provided. For the estimation of capitalcosts, it is suggested the use of appropriate “figures of merit”. The present review would be of interestfor researchers, technologists, engineers, and industrialists.
