Recent progress of modified CeO2-based materials for photocatalytic environmental remediation and antibacterial activity

Abstract

The rapid development of industrialization and urbanization has led to serious environmental pollution. As an environmentally friendly and sustainable energy source, solar-driven semiconductor photocatalysis has been widely applied in environmental remediation and antibacterial activity owing to its gentle reaction conditions. The use of CeO₂-based nanomaterials in green energy production, CO₂ conversion, pollutant degradation, and antibacterial is increasing. The photocatalytic performance of CeO₂ can be enhanced by appropriate modification strategies that suppress the rapid recombination of electron-hole pairs. This paper provides a systematic introduction to various modification strategies for CeO₂, and reviews the research progress of modified CeO₂ materials in photocatalytic CO₂ reduction, photocatalytic hydrogen evolution, heavy metal removal, photodegradation of organic pollutants, and antibacterial fields, finally offering perspectives on its future development direction.
