Solar fuel production from CO2 reduction in a self-biased hybrid solar-microbial device

Modelling of a CH4-producing microbial electrosynthesis system for energy recovery and wastewater treatment

“…As electrodes are usually thought to be solid, 8,35 the bioelectrochemical behaviors in region ② to ⑥ are considered, and the presented model relies on the following assumptions: 1) the biofilm/electrode interfaces are thought to be impermeable; 2) the thickness and intrinsic activity of the biofilms are unchanged over time and space; 3) HCO 3 − is the main carbon source for CH 4 production; 4) the dissolution and interconversion of CO 2 are in equilibrium; 5) the mass distribution in the bulk solution are homogeneous; 6) convection and electromigration in the electrolyte and biofilm are negligible; 7) the faradaic efficiency for CH 4 production is 90%; 5,36 and 8) the disturbances caused by gas production are gentle and have negligible influence on mass transfer.…”
