TiO₂ based Photocatalysis membranes: An efficient strategy for pharmaceutical mineralization

Area of Science:

• Environmental Science
• Materials Science
• Chemical Engineering

Background:

• Pharmaceuticals (PhACs) are emerging contaminants impacting water quality and posing risks to human and aquatic health.
• High mortality rates in COVID-19 patients consuming antibiotics highlight the urgent need to address PhACs in water.
• Current water treatment methods require innovative solutions for effective PhAC removal.

Purpose of the Study:

• To review the degradation of PhACs using photocatalysis combined with membrane filtration.
• To highlight the preparation and properties of TiO2-based nanomembranes for water purification.
• To discuss the mechanisms and reactor configurations for PhAC mineralization.

Main Methods:

• Review of literature on TiO2-based photocatalytic membranes for PhAC degradation.
• Analysis of PhAC mineralization mechanisms, including antibiotics and cytostatic compounds.
• Discussion of experimental reactor designs for commercial implementation.

Main Results:

• TiO2-based photocatalytic membranes offer an innovative strategy for PhAC mineralization.
• The review elaborates on the preparation and reinforcing properties of these nanomembranes.
• Degradation mechanisms and reactor configurations for PhAC removal are discussed.

Conclusions:

• TiO2-assisted membrane photocatalysis is a promising method for removing PhACs from water.
• Further research and development are needed to design effective nanomembrane prototypes for wastewater management.
• Commercial implementation requires optimized reactor designs for PhAC degradation.
