“…In wastewater treatment settings, TiO 2 photocatalysis in practical applications is very limited due to low quantum efficiency under visible radiations as well as difficulties of being separated in suspensions [18,55,56]. To ensure that TiO 2 will work optimally without any complexity, modification becomes essential [6,54].…”

Global accessibility to clean water has stressed the need to develop advanced technologies for the removal of toxic organic and inorganic pollutants and pathogens from wastewater to meet stringent discharge water quality limits. Conventionally, the high separation efficiencies, relative low costs, small footprint, and ease of operation associated with integrated photocatalytic-membrane (IPM) technologies are gaining an all-inclusive attention. Conversely, photocatalysis and membrane technologies face some degree of setbacks, which limit their worldwide application in wastewater settings for the treatment of emerging contaminants. Therefore, this review elucidated titanium dioxide (TiO2), based on its unique properties (low cost, non-toxicity, biocompatibility, and high chemical stability), to have great potential in engineering photocatalytic-based membranes for reclamation of wastewater for re-use. The environmental pathway of TiO2 nanoparticles, membranes and configuration types, modification process, characteristics, and applications of IPMs in water settings are discussed. Future research and prospects of magnetized TiO2-based membrane technology is highlighted as a viable water purification technology to mitigate fouling in the membrane process and photocatalyst recoverability. In addition, exploring life cycle assessment research would also aid in utilizing the concept and pressing for large-scale application of this technology.

“…An accumulation of PEG during the synthesis has notably improved the morphology and optical properties and enhanced the photocatalytic activity. 16,17 Based on the performance of mesoporous organosilicas, it seems worth carrying out tungstate separation from industrial wastewater to realize the tangible capabilities of the material. Moreover, after separation, the used material can be utilized as a photocatalyst to explore another potential application of photocatalytic degradation.…”

“…As an excellent photocatalyst, Ag 3 PO 4 has attracted intense interest due to its advantages of high quantum efficiency (>90%), superior oxidative ability, and simple preparation process. [ 11,12 ] Despite the fact that Ag 3 PO 4 possess superior properties, the disadvantages of readily formation irregular microstructure in the preparation process and photocorrosion in the photocatalytic process severely hamper its wide applications. [ 13 ] In order to overcome these weaknesses and improve its photocatalytic performance, numerous methods were adopted.…”

Semiconductor photocatalysis technology has aroused great interest in photocatalytic degradation, but it suffers from the drawbacks of fast electron‐hole recombination and unsatisfactory degradation efficiency. Herein, a novel photocatalyst Ag3PO4@NC with excellent photocatalytic activity is successfully prepared, characterized, and evaluated for the efficient removal of organic pollutants. After visible light irradiation for 5, 8, and 12 min, the photocatalytic degradation efficiency of norfloxacin, diclofenac, and phenol on the composite catalyst reaches 100%, and the apparent rate constant of which is 19.2, 48.7, and 23.2 times than that of the pure Ag3PO4, respectively. The density functional theory calculation results indicate that there is a built‐in electric field from N‐doped carbon (NC) to Ag3PO4 at the interface of the composite catalyst. Driven by the electric field, the photogenerated electrons of Ag3PO4 can be readily transferred to the NC, leading to the efficient separation of photogenerated carriers and the significant improvement of the catalytic performance. The results of radical trapping experiments and electron spin resonance analysis show that photogenerated holes and O2− play an important role in the photodegradation process. This work provides a universal strategy of construction built‐in electric field through coupling with NC to improve the photocatalytic performance of photocatalysts.
