abstract = {Sulfite-based advanced oxidation processes (s-AOP) have recently garnered
significant attention due to their ability to generate highly oxidative sulfate radicals and
eliminate contaminants from water. A state-of-the-art platform has been developed
through the synergistic combination of s-AOP and photocatalysis under visible light as
weak as ambient indoor daylight. This platform achieved an enhanced degradation
efficiency for defect-engineered CeO2 nanocubes by using sodium sulfite instead of
SO2, 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 orange
degradation have been investigated. The CeO2/Na2SO3/vis-light platform exhibits
promising prospect as a system to enhance conventional s-AOP in wastewater treatment
or disinfection. It demonstrates excellent performance in terms of pH sensitivity, anion
influence, and resistance to leaching. This highlights its significant potential for
practical applications and future process scale-up.},
