Improving the ORR catalytic performance of hollow porous carbon derived from F127 assembled in ethanol-hexane mixture containing Fe3+ ion

To reduce the cost of fuel cell oxygen reduction reaction catalysts, the gels of polyethylene oxide-polypropylene oxide-polyethylene oxide (PEO-PPO-PEO) triblock copolymer (F127) and Fe(NO 3 ) 3 ·9H 2 O, formed in ethanol-hexane mixture by sol–gel method, were pyrolyzed to prepare the iron-doped car...
