“…Ishibashi et al [ 95 ], Amao et al [ 86 ], and Ikeyama et al [ 94 ], for example, used photochemical regeneration in the presence of TEOA as an electron donor. Although this type of regeneration performed on the cofactor analog rather than the natural cofactor seems to be easier and more efficient, the need to include several molecules in the system, such as the photosensitizer and an electron donor, makes the final separation difficult [ 63 ].…”

The need to decrease the concentration of CO2 in the atmosphere has led to the search for strategies to reuse such molecule as a building block for chemicals and materials or a source of carbon for fuels. The enzymatic cascade of reactions that produce the reduction of CO2 to methanol seems to be a very attractive way of reusing CO2; however, it is still far away from a potential industrial application. In this review, a summary was made of all the advances that have been made in research on such a process, particularly on two salient points: enzyme immobilization and cofactor regeneration. A brief overview of the process is initially given, with a focus on the enzymes and the cofactor, followed by a discussion of all the advances that have been made in research, on the two salient points reported above. In particular, the enzymatic regeneration of NADH is compared to the chemical, electrochemical, and photochemical conversion of NAD+ into NADH. The enzymatic regeneration, while being the most used, has several drawbacks in the cost and life of enzymes that suggest attempting alternative solutions. The reduction in the amount of NADH used (by converting CO2 electrochemically into formate) or even the substitution of NADH with less expensive mimetic molecules is discussed in the text. Such an approach is part of the attempt made to take stock of the situation and identify the points on which work still needs to be conducted to reach an exploitation level of the entire process.

Visible‐light driven CO2 reduction to formate with the system consisting of water‐soluble zinc tetraphneylporphyrin tetrasulfonate (ZnTPPS), formate dehydrogenase from Candida boidinii (CbFDH) and 1‐nicotinamidethy‐1’‐methyl‐4,4’‐ bipyridinium salt (NEMBP) in the presence of triethanolamine (TEOA) as an electron donor was investigated. NEMBP was prepared as the 4,4’‐BP with the nicotinamide‐group to promote the improvement of affinity with CbFDH. The properties of NEMBP were characterized by photochemical and electrochemical methods. In order to evaluate the affinity between cation radical of NEMBP (NEMBP+.), as a co‐enzyme and CbFDH, the energy level based on simple docking simulation and density functional theory were estimated. It was speculated that NEMBP+. could bind near the substrate binding pocket of CbFDH as well as NAD+ by docking simulation. In the visible‐light driven NEMBP reduction with the sensitization of ZnTPPS in the presence of TEOA, the yield for reduction of NEMBP to NEMBP+. was estimated to be 80%. In the CO2 reduction to formate with the system consisting of TEOA, ZnTPPS, NEMBP and CbFDH, the turnover numbers of NEMBP and CbFDH were estimated to be 0.14 and 1.53 h−1, respectively.

“…Some of these systems have been developed into visible light responsive hydrogen production systems . We also have been reported the light‐driven CO 2 reduction to formate with the system of a semiconductor based photocatalyst TiO 2 nanoparticle as an effective photosensitizing material, MV and FDH in the presence of triethanol amine (TEOA) as an ED . To develop the light driven CO 2 reduction to formate with TiO 2 , MV, FDH and water as an electron donor, it is necessary to suppress the reaction between oxygen production due to water photolysis and MV .…”

Efficient sacrificial reagent free (and no external bias) photoelectrochemical CO 2 reduction to formate with a hybrid system consisting of semiconductor-based photocatalytic TiO 2 nanoparticles, methylviologen (MV) as an electron carrier, and biocatalytic formate dehydrogenase (FDH) was investigated. To develop the sacrificial reagent free photoelectrochemical cell for the CO 2 reduction to formate, the photoanode based on TiO 2 film and cathode based on the carbon fabric paper (CFP) were separated into two compartments using a protonpermeable Nafion film to prevent gas diffusion. When the anode was irradiated with Xenon lamp (> 300 nm), MV reduction and CO 2 reduction to formate with FDH on the cathode side proceeded in this system. For MV reduction with photoelectrochemical cell, MV was reduced using TiO 2 film at each pH (6, 7 and 8) without bias, the reduction of MV did not progressed at pH 6. In contrast, MV reduction was progressed at pH 7 or 8. For CO 2 reduction to formate in the presence FDH on the cathode side with photoelectrochemical cell, the rate of formate production was estimated to be 31.9 nmol h À 1 at pH 8 under continuous irradiation without bias. Moreover, the rates of formate production at pH 7 and 8 were estimated to be 56.5 and 168.8 nmol h À 1 , respectively under continuous irradiation with bias (0.4 V vs. cathode). By using this system, we have succeeded in constructing CO 2 reduction to formate using water as an electron donor, which does not require a sacrificial reagent.[a] T. Figure 1. Formic acid-CO 2 conversion catalyzed with FDH in the presence of natural co-enzyme NAD + /NADH redox coupling.
