Rationally constructing nitrogen–fluorine heteroatoms on porous carbon derived from pomegranate fruit peel waste towards an efficient oxygen reduction catalyst for polymer electrolyte membrane fuel cells

Autor: Srinu Akula, Prabakaran Varathan, Rahul S. Menon, Akhila Kumar Sahu

Publikováno v: Sustainable Energy & Fuels. 5:886-899

N and F heteroatom dual-doping is directed to regulate the defects and texture of porous carbon derived from pomegranate fruit peel wastes (N–F/PGPC), and is responsible for creating active sites favorable for oxygen reduction reaction (ORR). The N
