Sp-hybridized carbon- facilitated peroxymonosulfate activation for superior phenolic pollutant removal.

Carbocatalysts, widely regarded as eco-friendly catalysts in the field of peroxymonosulfate (PMS) activation for pollutant removal, exhibit significant variations in performance depending on the type of carbon atom hybridization. Notably, the novel graphdiyne (GDY), characterized by its sp-hybridized carbon (sp-C), has recently garnered significant attention. However, the precise mechanistic role of sp-C on PMS activation remains unclear.
