摘 要:Chemically modified carbonaceous materials have attained utmost attention in the fields of renewable energy storage and conversion,due to the controllable physicochemical properties,tailorable micro-/nanostructures,and respectable ***,P-doped mesoporous carbons were synthesized by using F127 as the soft template,organophosphonic acid as the P source and phenolic resin as the carbon *** amounts of iron species were introduced to act as a graphitization *** synthesized carbons exhibit the well-defined wormhole-like pore structure featuring high specific surface area and homogenously doped P ***,introducing iron species during the synthesis process can optimize the textural properties and the degree of graphitization of carbon *** doping amount of P has an important effect on the porous structure and the defect degree,which correspondingly influence the active sites and the oxygen reduction reaction(ORR)*** resultant material presents superior catalytic activity for the ORR,together with remarkably enhanced durability and methanol tolerance in comparison with the commercial Platinum catalyst,demonstrating the possibility for its use in electrode materials and electronic nanodevices for metal-air batteries and fuel cells.
