Hollow Cu-Co/N-doped carbon spheres derived from ZIFs as an efficient catalyst for peroxymonosulfate activation

Zeolitic imidazolate framework (ZIF)-derived carbons have been considered promising catalysts for the degradation of organics in water through peroxymonosulfate (PMS)-based oxidation processes. The construction of hierarchical hollow, porous structures while retaining the properties of ZIF-derived carbons is highly desirable for a catalyst but remains an arduous challenge. Herein, ZIF-67 (Co(mim)2, mim = 2-methylimidazolate) derived carbon with...
