Energetic metal–organic frameworks derived porous nitrogen-doped carbon nanocages for highly efficient peroxymonosulfate activation

Energetic metal–organic frameworks derived porous nitrogen-doped carbon nanocages are applied as highly efficient Fenton-like catalyst for degradation of micropollutants. [Display omitted] •Porous N-doped carbon nanocages (PNCCs) are prepared by pyrolyzing energetic MET-6.•PNCCs-900 presents a high N-doping level of 13.1%.•The graphitic N ratio can be regulated by varying the pyrolysis temperature.•The graphitic N in PNCCs-900 serve as active sites for PMS activation. Porous nitrogen-doped carbon nanocages (PNCCs) are fabricated by one-step pyrolysis of energetic Zn-based MOF (MET-6) and employed as highly efficient PMS activator to decompose organic micropollutants. PNCCs-900 exhibits extraordinary catalytic activity for RhB degradation due to its high specific surface area (894.9 m2 g−1), N-doping level (13.1%), and optimum N configuration ratio. This work opens a new avenue for the development of efficient PMS activators for water remediation.
