Hybrid Technologies for an Enhanced Carbon Recycling Based on the Enzymatic Reduction of CO2 to Methanol in Water: Chemical and Photochemical NADH Regeneration

Rocking chair enzyme: Chemical reducing agents (sodium dithionite) or bioglycerol (as H and e-donor under irradiation in the presence of ZnS-A as photocatalyst) are able to back-convert NADP+ into NADPH, which is used as e-donor in the enzymatic reduction of CO2 into CH3OH. In doing so, the molar ratio CH3OH/CO2 has been increased (without recycling of NADP+) using the photocatalyst.
