Abstract

Heterogeneous photocatalysis is a process with great potential for pollutant abatement. However, its application in practical water treatment systems has been very limited. On the other hand, biotemplating is an effective strategy to obtain morphology controllable materials with structural specialty, complexity, and related unique properties. In this chapter, we summarize a few wastewater photocatalytic reactors based on biotemplated photocatalysts. They have been successfully used in the treatment of lignite gasification wastewater, wastewater at the expressway service area, and hydropower stations. The design, assembly, and manufacturing of skid-mounted photocatalytic reactors will also be described. Finally, the future challenges and opportunities for photocatalytic wastewater treatment are discussed.
