B-Bridge Regulated Asymmetric Dual-Atomic Catalysts for Synergistically Enhanced Styrene Mineralization and CO2 Reduction

• Bifunctional NiFe-BNC catalyst achieves simultaneous 99% styrene degradation and 98% CO Faraday efficiency at 1000 mA cm−2. • Boron incorporation acts as an electron bridge, enhancing interfacial electron transfer and optimizing CO2 adsorption. • The catalyst exhibits 6-fold higher CO2 adsorption capacity compared to boron-free counterpart. • This work demonstrates a sustainable waste-to-fuel strategy for carbon cycle utilization.
