COF‐Derived N,P Co‐Doped Carbon as a Metal‐Free Catalyst for Highly Efficient Oxygen Reduction Reaction

Abstract

A new kind of metal‐free, porous, and N,P co‐doped carbon catalyst was prepared from a high crystalline and two dimensional (2D) covalent organic framework (COF). Remarkably, this N,P co‐doped catalyst exhibits an excellent tolerance towards methanol crossover, as well as a comparable oxygen reduction reaction performance to commercial Pt/C.

A Defect‐rich N, P Co‐doped Carbon Foam as Efficient Electrocatalyst toward Oxygen Reduction Reaction

“…[20] P doping also enhances edge defects by introducing surface defects. [21] Theoretical analysis further revealed that edge-doped sites with N, P dopants are more efficient to improve ORR, compared with the inner doped ones, highlighting synergistic effect of edge defects and heteroatom doping. [13] Additionally, the well-balanced pore structure, high surface area and good conductivity are also of importance in boosting the catalytic performance of an electrocatalyst.…”

Challenges for large scale applications of rechargeable Zn–air batteries

“…192,193 There have been many breakthrough applications for this technology in batteries. 192,[194][195][196][197][198][199] Wang et al 200 reported a new metalo-covalent organic framework doped with Ag/Ag 2 O. This MCOF combines the advantages of MOFs and COFs and provides excellent OER and ORR performance through synergistic interaction between Co, O, N, Ag/Ag 2 O and a nano-ower-like structure, as shown in Fig.…”

Heteroatom doped M–N–C single-atom catalysts for high-efficiency oxygen reduction reaction: regulation of coordination configurations

“…58,62,63 So far, numerous studies have shown that P-doped nonmetal carbon based ORR catalysts show excellent ORR activity. 64,65 Yang et al 60 synthesized a kind of N and P co-doped non-metal carbon catalyst, and its active structure was Fig. 2 (a) The P-doping configuration.…”
