Urea holds promise as an alternative water-oxidation substrate in electrolytic cells. High-valence nickel-based spinel, especially after heteroatom doping, excels urea oxidation reactions (UOR). However, traditional spinel synthesis methods with prolonged high-temperature lack kinetic precision, hindering the balance between controlled doping and highly active two-dimensional (2D) porous structures design. This significantly impedes identification of electron configuration-dependent sites doped 2D spinels. Herein, we present a microwave shock method for preparation NiCo2O4 spinel. Utilizing transient on-off property pulses precise structural design, non-metal (boron, phosphorus, sulfur) distinct extranuclear disparities serves straightforward examples investigation. Precise tuning lattice parameter reveals impact covalent bond strength on stability. The introduced defect levels induce unpaired d-electrons transition metals, enhancing adsorption electron-donating amino groups molecules. Simultaneously, Bode plots confirm mechanism rapid migration caused by reduced band gaps UOR activity. prepared phosphorus-doped NiCo2O4, optimal configuration control, outperforms most reported modification strategy advances understanding theoretical structure-activity mechanisms high-performance spinels UOR.
