The metallic Ni nanoparticles formed during pyrolysis acted simultaneously as active sites and electron accumulation hubs. Furthermore, the strong interfacial interactions of SiC/Ni-MOF type-II heterojunction and Schottky barrier between Ni and SiC facilitated efficient charge transfer across the interfaces. The coexistence of defective C and graphitic C optimized the adsorption of CO₂ and electron transport.

Both experimental and theoretical investigations demonstrate that the low electronegativity of boron induces charge redistribution at the cobalt sites, thereby synergistically enhancing charge transfer dynamics and lowering proton transfer barriers. This facilitates the selective generation of high-valent cobalt-oxo species (Co(IV)<img>O) and singlet oxygen (¹O₂) as predominant non-radical oxidants, effectively circumventing scavenging effects by background anions.

Furthermore, it maintains over 80% efficiency across a broad pH range (3–11) and in complex matrices, such as wastewater containing 5 mM Cl⁻/CO₃²⁻. Quantitative structure-activity relationship analyses reveal strong correlations between contaminant degradation kinetics and molecular descriptors, including hydrophilicity, energy gap (ΔE), and electrophilicity index. Importantly, a continuous-flow reactor employing immobilized SA-Co-BN exhibits operational stability for 680 min with 80% contaminant removal, while toxicity assessments confirm a significant reduction in the ecotoxicity of degradation intermediates.

The approach enables orientation-designed and π-π interaction-driven in-situ growth of DOL-COF nanosheets on reduced graphene oxide (rGO) scaffolds.
