AB Sulfite-based advanced oxidation processes (s-AOP) have recently garneredsignificant attention due to their ability to generate highly oxidative sulfate radicals andeliminate contaminants from water. A state-of-the-art platform has been developedthrough the synergistic combination of s-AOP and photocatalysis under visible light asweak as ambient indoor daylight. This platform achieved an enhanced degradationefficiency for defect-engineered CeO2 nanocubes by using sodium sulfite instead ofSO2, resulting in a synergy factor of up to 88%. The reaction pathways, intermediates,ion leaching and the possible influence of aqueous conditions during the methyl orangedegradation have been investigated. The CeO2/Na2SO3/vis-light platform exhibitspromising prospect as a system to enhance conventional s-AOP in wastewater treatmentor disinfection. It demonstrates excellent performance in terms of pH sensitivity, anioninfluence, and resistance to leaching. This highlights its significant potential forpractical applications and future process scale-up.
