Biotic-abiotic hybrid systems (BAHs) constructed by integrating biological methanogens with photocatalysts offer novel approaches for the effective solar-driven conversion of CO2 to CH4, providing significant inspiration achieving carbon neutrality and alleviating energy crisis. As metal would cause photocorrosion that damages microbial cells lead system imbalance. Therefore, exploring suitable metal-free is particular importance in search more efficient sustainable BAHs improve actual operability applicability. Herein, black phosphorus/carbon nitride (BPCN x ) as an alternative heterostructure was combined Methanosarcina barkeri (M. barkeri) construct M. barkeri-BPCN systems, their cyclic methanogenesis performance investigated. Our results demonstrated BPCN promotes separation photogenerated charges enhances quantum yield, a sustained source cyclically driven reduction CH4 under visible light. achieved total yield 1087.45 ± 29.14 μmol gcat-1 after three cycles, 1.96 times higher than barkeri-Ni@CdS. overcame defects photocatalyst kept cell permeability, stability effectively maintaining activity barkeri. These highlight viable role construction methanation CO2, which conducive development environmentally-friendly, low-cost, strategy CH4.
