Ultrafast removal of organics via peroxymonosulfate activation over Co 2 P/TD hollow spheres derived from ZIF-67.

Co 2 P/tetrasodium diphosphate (TD) derived from ZIF-67/sodium phytate was newly developed and synthesized, and exhibited excellent degradation ability toward various refractory organics via peroxymonosulfate activation. A corresponding reaction mechanism was proposed. In addition, a continuous-flow operation of phenol degradation was realized.
