Semiconductor photocatalysis is a newly emerging technology for the elimination of harmful chemical compounds from air and water. It couples low‐energy UV light with semiconductors acting as photocatalysts. Although extensive laboratory‐scale studies have proven the potential of this promising technology to destroy toxic pollutants dissolved or dispersed in water, technical development to pilot‐scale level has not yet been successfully achieved. In this paper, the challenges that need to be addressed for the scale‐up of multiphase photocatalytic reactors are discussed.
