Noble-metal alloys are high-efficiency two-electron oxygen reduction reaction (2e– ORR) catalysts for the electrochemical production of H2O2. However, development noble-metal H2O2 is still in a bottleneck period due to their high cost, toxicity, low atom utilization, and limited reactivity. To solve these dilemmas alloys, developing non-noble can be an alternative. Herein, BiNi with uniform diameter ∼11 nm supported on carbon nanosheets (BiNi/C) synthesized by hydrothermal-pyrolysis method. The BiNi/C material exhibits 2e– ORR performance onset potential 0.76 V vs RHE selectivity ∼98% 0.1 M KOH. H-cell tests deliver yield ∼17 mM within 2 h at 0.4 RHE. then used fixed-bed Fenton process, degradation efficiencies RhB BPA maintain 100% ∼95% 10 h, respectively. Theoretical calculations reveal that Bi regulate electronic structure Ni through "dual-isolation" effect physical isolation. adsorption energy *OOH thus deceased, side-on sites achieved. Furthermore, itself lowest overpotential also serve as active site generation dual-isolation effect. Our study provides guidance synthesis alloy activity selectivity.
