Nonradical oxidation in persulfate activation by graphene-like nanosheets (GNS): Differentiating the contributions of singlet oxygen (1O2) and sorption-dependent electron transfer

Nonradical reactions induced by nanocarbon-driven peroxydisulfate (PDS) activation recently emerge a promising strategy of groundwater remediation or wastewater treatment, whereas the involved reaction pathways remain controversial. We here investigate and differentiate the two representative nonradical mechanisms of PDS activation on graphene-like nanosheets (GNS). The template-induced GNS exhibited a high porosity of over 1200 m2 g−1 and a...
