Copper foam supported g-C₃N₄-metal-organic framework bacteria biohybrid cathode catalyst for CO₂ reduction in microbial electrosynthesis.

ABSTRACT: Microbial electrosynthesis (MES) presents a versatile approach for efficiently converting carbon dioxide (CO₂) into valuable products. However, poor electron uptake by the microorganisms from the cathode severely limits the performance of MES. In this study, a graphitic carbon nitride (g-C₃N₄)-metal-organic framework (MOF) i.e. HKUST-1 composite was newly designed and synthesized as the cathode catalyst for MES operations. The physiochemical analysis such as X-ray diffraction, scanning electron microscopy (SEM), and X-ray fluorescence spectroscopy showed the successful synthesis of g-C₃N₄-HKUST-1, whereas electrochemical assessments revealed its enhanced kinetics for redox reactions. The g-C₃N₄-HKUST-1 composite d
