Abstract

Advanced oxidation processes utilizing sulfate radicals have attracted growing interest in recent years as a clean and efficient method for breaking down organic pollutants. Cerium is widely recognized for its reversible redox reaction involving Ce(III) and Ce(IV) species. This distinctive characteristic enhances the breakdown of organic pollutants by persulfate, a chemical that contains sulfate radical species, through the release of oxygen and the formation of oxygen vacancies within its structure. Multiple strategies have been employed to improve the effectiveness of persulfate activation and the degradation of organic compounds. This review uniquely focuses on cerium-based catalysts, addressing their underexplored potential in persulfate activation. It offers a comprehensive summary of design strategies, elucidates the synergistic mechanisms between Ce ions, support materials, and persulfate, and systematically evaluates their applications. Economical feasibility was also analyzed as well as providing actionable recommendations to advance catalysts research and implementation in environmental treatment.

期刊介绍： The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
