π-π Stacked step-scheme PDI/g-C3N4/TiO2@Ti3C2 photocatalyst with enhanced visible photocatalytic degradation towards atrazine via peroxymonosulfate activation

In this study, a novel π-π stacked PDI/g-C3N4/TiO2@Ti3C2 photocatalyst with step-scheme (S-scheme) heterojunction was constructed to boost the atrazine (ATZ) photocatalytic degradation by activating peroxymonosulfate (PMS). The π-π interaction in the PDI/g-C3N4 induced the delocalization of the photoelectrons, therefore promoted their migration. Meanwhile, the intimate contact and the staggered band configurations between the PDI/g-C3N4 and...
