摘要： Microbial electrosynthesis (MES) is an attractive technology for converting CO2 into chemicals. In this technique, electrons are acquired either directly or indirectly through H2 in the cathode. Shewanella oneidensis MR-1 can perform hydrogen evolution reaction via reverse electron transfer at the cathode. In this study, the self-assembly of graphene oxide and S. oneidensis MR-1 formed a conductive bio-abiotic composite as a cathode for MES with Clostridium ljungdahlii, obtaining more biocatalysts for hydrogen evolution and enhancing electron transfer rate. The average H2 production rate with the conductive bio-abiotic composite was 41.51 +/- 2.54 x 102 mol d-1, while the undecorated carbon felt was 12.96 +/- 1.09 x 102 mol d-1. Consequently, acetate and butyrate yields were 0.18 g L-1 d-1 and 0.07 g L-1 d-1, which increased by 2.1 and 1.7 times those of the control, respectively. This work provides new opportunities for constructing a highly efficient cathode via biotic-abiotic hybrid composite for improving MES performance.
