Summary: Layered double hydroxides (LDHs) serve as versatile platforms for modulating the electronic structure of earth-abundant transition metal-based electrocatalysts for various energy-related reactions. This study demonstrates the use of electrodeposited Ni-Co-Fe LDHs on Ni nanocones-decorated Ni foam as a template for the electrosynthesis of NiCoFeB from a K2B4O7 solution. The resulting amorphous tri-metal borate (TMB) exhibits excellent electrocatalytic activities for HER, OER, and ORR, as well as high durability. A zinc-air battery using TMB@NiNC dual oxygen catalyst cathode shows superior performance compared to commercial noble metal benchmarks.
