摘　　要：TiO_(2)is one of the best-known environmentally friendly photocatalysts that has demonstrated the great potential to degrade a wide variety of organic foulants in water and wastewater treatment when placed under UV radiation.Currently,TiO_(2)-based photocatalytic membranes are at the forefront of photodegra-dation research and technical readiness.The membrane setup provides a high contact surface area for ef-fective filtration and degradation,without the necessary hassle of photocatalyst recovery after water and wastewater treatment.Meanwhile,TiO_(2)photocatalytic ceramic membranes have become an emerging re-search area due to the inherent chemical and mechanical stability of ceramic membranes,which enables them to outperform polymeric membranes.With the recent shift from polymeric to ceramic membranes in industrial applications,TiO_(2)photocatalytic ceramic membranes will become a key player among the next-generation ceramic membranes,as they are capable of multiple functionalities.This review provides a timely and focused investigation into the fabrication and application of such TiO_(2)photocatalytic ceramic membranes for water and wastewater treatment.The benefits of using photocatalytic ceramic membranes in filtration,such as a higher foulant removal efficiency,higher water permeability,and much improved antifouling capabilities,are highlighted and explained.Finally,the current research,technical readiness,and remaining gaps are identified,and a set of critical insights are provided using the available data to guide the developmental pathway of practical TiO_(2)photocatalytic ceramic membranes for water and wastewater treatment.
