High conductive polymer PANI link Bi₂MoO₆ and PBA to establish “tandem hybrid catalysis system” by coupling photocatalysis and PMS activation technology
Abstract
In order to design an efficient advanced oxidation system to improve the inherent limitations in removing refractory organic pollutants, we couple photocatalysis and peroxymonosulfate (PMS) activation technology to establish a tandem hybrid catalysis system inspired by series hybrid electric vehicles. Among them, Bi₂MoO₆, as an electric power source, can be driven by fuel (light) to generate continuous power (electron) input into the prussian blue analogues (PBA) through the transmission shaft polyaniline (PANI), allowing it to respond quickly and continuously activate PMS. Therefore, it exhibits excellent catalytic performance to degrade DC increased by 55%, and the catalytic rate constant k increased by 7 times compared with the PMS alone. Continuous flow experiments are explored to reveal the feasibility of engineering applications. This study provides a new strategy of tandem hybrid catalysis system to drive future advanced water treatment technologies. Show more
