| 摘要 | The rational design of efficient oxygen reduction reaction (ORR) catalysts with maximized atom utilization is essential for advancing the oxygen depolarized cathode technology. Here, we report atomically dispersed Fe, P heteronuclear catalytic pairs on hierarchical porous carbon, in which the hydrogen bond between Fe, P catalytic pairs and ORR intermediates significantly enhances the adsorption/desorption kinetics and lowers the rate-determining step barrier of OH* desorption. Thus, Fe,P/HPC delivers an alkaline ORR performance with a half-wave potential (E1/2) of 0.92 V and retains ∼90% of the initial activity even after 150 h operation. In addition, Fe,P/HPC achieves an E1/2 of 0.74 V in 0.1 M HClO4. The Fe,P/HPC-based aqueous Zn–air battery (A-ZAB) achieves a high power density of 262 mW cm–2 and exhibits enhanced stability, sustaining a minimal voltage gap over 2800 h of constant-current cycling. Moreover, the quasi-solid-state Zn–air battery (QSS-ZAB) delivers a large open-circuit voltage of 1.52 V, while maintaining a cycling stability for over 95 h at 0.5, 1, and 2 mA cm–2, respectively. In the chlor-alkali process, the Fe,P/HPC||RuO2 electrolyzer enables a large current density of 300 mA cm–2 at 1.66 V and maintains stability over 110 h. The present work pioneers the designing and construction of atomic-level heteronuclear catalysts for practical and durable cathode. |
