Abstract Direct electron transfer (ETP) during peroxymonosulfate (PMS) activation enables selective, matrix-resistant organic contaminants oxidation, yet its precise control over competing radical pathways remains elusive. Here we report a nano-island-like single-atom catalyst- carbon nitride islands immobilize cobalt single atoms on reduced graphene oxide (CoN3C/rGO)- that leverages an island-sea architecture to direct PMS activation toward ETP.

Abstract Per- and polyfluoroalkyl substances (PFAS) resist most remediation technologies because of their exceptionally inert carbon–fluorine bonds. Here we report a visible-light Z-scheme photocatalyst composed of CuInS2 quantum dots anchored on BiOCl nanoplates (CuInS2/BiOCl) that overcomes this barrier.

1 Introduction Per- and polyfluoroalkyl substances (PFASs) have been widely used due to their unique properties, such as the simultaneous oleophobicity and hydrophobicity as surfactants (Buck et al., 2011). The carbon-fluorine (C-F) skeleton is highly resistant to most forms of oxidation; hence the chemical or biological degradation is often difficult (Wang et al., 2014b; Trojanowicz et al., 2018).
