Abstract
The delicate design and fabrication of transition metal-based heterostructures with abundant active sites are a crucial issue for achieving superior electrocatalytic properties. In this work, we introduce a novel bio-assisted strategy for assembling cobalt-based heterostructures on nitrogen and phosphorus codoped carbon nanobelts, which serve as highly efficient bifunctional oxygen catalysts. The fungus of Rhizopus is utilized to encapsulate the Co-CoTe within the in-situ formed nitrogen and phosphorus codoped carbon nanotubes (NPCNT), resulting in hairy nanobelts with a porous structure and excellent flexibility. Both experimental and theoretical analyses results reveal the superior geometric configuration, electronic structure, and the low energy barrier of the bio-Co-CoTe@NPCNT nanobelts. Benefitting from these advantages, the bio-Co-CoTe@NPCNT nanobelts demonstrate rapid kinetics, impressive catalytic performance, and high durability in both oxygen evolution and reduction (OER/ORR) reactions. The aqueous zinc-air batteries (ZAB) employing the prepared bio-Co-CoTe@NPCNT nanobelt cathode exhibit the stable cycling properties and good reliability. Furthermore, the solid-state ZAB demonstrates high reliability, pliability, and durability under various deformations.

J Colloid Interface Sci 2025; 679:947-956.

Abstract
The design of highly efficient catalysts to enhance the kinetics of oxygen reduction (OER) and oxygen evolution (ORR) reactions is the key issue for the development of high-performance Zn-air battery. In this work, we report the design of Co-CoTe heterostructured fibers as the bifunctional oxygen catalyst for Zn-air battery. Firstly, the theoretical analysis was carried out on Co-CoTe heterostructure. The large work function difference is favorable to construct strong interfacial built-in electric field (BIEF), and the low energy barrier endows high catalytic activities. Moreover, the in-situ grown carbon shell was designed to build "core-shell" Co-CoTe/C unit to realize its high performance. They assemble the Co-CoTe@HFS fiber with good self-supporting and flexible features. Taken the advantages of the strong BIEF, the "core-shell" basic unit, and the freestanding substrate, the Co-CoTe@HFS fiber achieves the good electrocatalytic properties and high reliability. The full Zn-air battery (ZAB) with the Co/CoTe@HFS air cathode achieves the high peak power density and cycling stability over long-term cycling. Therefore, this work provides a clue to design bifunctional oxygen catalysts for high-performance ZABs.
