Preparation of hydrogel-based photocatalytic composite materials by radiation technology

Abstract

To overcome the disadvantage of regular photocatalysts that lack favorable recyclability, hydrogel has become an excellent carrier for photocatalysts. Hydrogel-based photocatalytic composites have the advantages of super-absorbency and recyclability. They can be widely used in the environmental treatment and in medical and health fields. As one of the preparation methods of hydrogel-based photocatalytic composites, ionizing radiation technology is simple, safe, and pollution-free; it can be applied to the industrial production of hydrogel-based photocatalytic composites. This paper summarizes the characteristics of the ionizing radiation technology, the classification of hydrogel-based photocatalytic composites, and radiation preparation methods and their applications. Further, it provides an outlook on future research directions in light of the current research status of hydrogel-based photocatalytic composites.
