Utilizing affordable bifunctional catalysts per strong ORR/OER (oxygen reduction and evolution reactions) ability superior zinc-air battery performance is yet difficult due to the diverse mechanisms of ORR/OER. This work uses CoNi-MOF (metal-organic framework) as a self-template yield CrS doped CoNi/C catalyst. Comparable Pt/C IrO2 commercial catalysts, CrS@CoNi/C catalyst exhibits improved electrocatalytic activity toward OER ORR its linked pellet architecture intact metal sulfide@carbon structure. The has most intriguing performance, with significantly lower potential an exceptionally extended cycle duration (E1/2 = 0.72 V η10 260 mV). CrS@CoNi/C-based aqueous shows long-term charge-discharge stability (more than 100h/600 cycles) together significant specific capacity (789.7 mAh g-1 Zn) power density (132.2 mW cm-2). Most significantly, after stability, recharged alkaline been employed exhibit less structural deformation for cathode more zincate ion production anode side electrodes, which through TEM analysis.

Abstract High‐performance bifunctional electrocatalyst for oxygen evolution reaction (OER) and reduction (ORR) is the keystone industrialization of rechargeable zinc‐air battery (ZAB). In this work, modulation in spin state Fe single atom on nitrogen doped carbon (Fe 1 ‐NC) devised by Co 3 O 4 (Co @Fe ‐NC), a mediate recorded. Besides, d band center downshifted associated with increment e g filling revealing weakened interaction OH * moiety, resulting boosted ORR performance. The kinetic current density ‐NC 2.0‐ 5.6 times higher than commercial Pt/C, respectively. Moreover, high found contributing to accelerated surface reconstruction witnessed operando Raman electrochemical impedance spectroscopies.

Abstract To enhance the electrochemical synthesis of ammonia performance by accelerating reaction kinetics electrocatalytic Nitrate reduction (NO 3 − RR), it is crucial to develop electrocatalysts with high acitiity and selectivity NO RR. Herein, a Ru‐doped Co‐Ti C 2 catalyst was prepared for RR in this work. In 0.1 M KOH & KNO electrolyte, Ru doped (nRu:nCo = 2:8, RuCo‐Ti ‐2:8) achieved Faraday efficiency (FE) 96.48% an yield 2261.99 µg cm −2 h −1 at −0.4 V vs. RHE. Compared Co‐MXene catalysts other compositions, ‐2:8 exhibited better FE. Moreover, excellent stability
