Abstract

En 中文

• The combination of Chlorella with the optimal Fe/Ni-MOFs system (Fe1Ni1@(BTEC)(bipy)) has been successfully fabricated. • The incorporation of Chlorella enhances the methane yield to 5.0 times that of Fe1Ni1@(BTEC)(bipy) alone. • The Fe1Ni1@(BTEC)(bipy) interacts with Chlorella through electrostatic adsorption and covalent bonding. • Chlorella's ability to capture light and the microenvironmental CO2 under strong illumination are significantly enhanced. • The Fe1Ni1@(BTEC)(bipy)-Chlorella composite system represents an effective method for enhancing methane production.
