Pyrolysis Enzymolysis-Treated Pomelo Peel: Porous Carbon Materials with Fe-N_x Sites for High-Performance Supercapacitor and Efficient Oxygen Reduction Applications.

ABSTRACT: This paper proposes a different strategy for deriving carbon materials from biomass, abandoning traditional strong corrosive activators and using a top-down approach with a mild green enzyme targeted to degrade the pectin matrix in the inner layer of pomelo peel cotton wool, inducing a large number of nanopores on its surface. Meanwhile, the additional hydrophilic groups produced via an enzymatic treatment can be used to effectively anchor the metallic iron atoms and prepare porous carbon with uniformly dispersed Fe-N_x structures, in this case optimizing sample PPE-FeNPC-900's specific surface area by up to 1435 m² g^-1. PPE-FeNPC-900 is used as the electrode material in a 6 M KOH electrolyte; it manifests a decent specific capacitance of 400 F g^-1
