Abstract
Back cover image: Traditionally, expensive precious metal based electrocatalysts have been relied upon as air electrodes for rechargeable zinc air batteries (ZABs), which have prompted researchers to innovate and develop cost-effective and efficient novel bifunctional electrocatalytic systems. In the article number cey2.457, Jiang and co-workers reported Co/CoO heterojunction nanoparticles (NPs) rich in oxygen vacancies embedded in mesoporous walls of nitrogen-doped hollow carbon nanoboxes coupled with nitrogen-doped carbon nanotubes (P-Co/CoOV@NHCNB@NCNT) as bifunctional electrocatalysts synthesized through zeoliteimidazole framework (ZIF-67) carbonization, chemical vapor deposition and O2 plasma treatment. It displays exceedingly good electrocatalytic performance for oxygen reduction reactions (ORR) and oxygen evolution reactions (OER), significantly superior to standard noble metal-based Pt/C + RuO2 systems. The enhanced electrocatalytic performance of the P-Co/CoOV@NHCNB@NCNT can be attributed to the formation of heterojunctions and oxygen vacancies induced by O2 plasma treatment.
