This review focuses on the production of liquid fuels using solar energy combined with their use in direct liquid fuel cells. The production of formic acid, which is the two-electron reduced product of CO 2 , as a solar liquid fuel as well as a hydrogen storage material is discussed together with its use in direct formate fuel cells. Other CO 2 reduction products such as methanol and formaldehyde as solar liquid fuels as well as hydrogen storage materials are reviewed with the performance of the corresponding fuel cells. The production of nitrogen fixation products such as ammonia and hydrazine is also reviewed together with their fuel cells. Finally, the production of hydrogen peroxide from not only pure water but also seawater and dioxygen in the air using solar energy is discussed and combined with the recent development of one-compartment hydrogen peroxide fuel cells.

“…The interest in the utilization of CO 2 as readily available feedstock is experiencing a growing momentum in both academia and industry. [1][2][3][4][5][6] Carbon dioxide can be "harvested" in high concentration at numerous point sources worldwide facilitating the implementation of carbon capture and utilization (CCU) concepts, 7,8 including the use of CO 2 as C1-building block for chemical synthesis as an equally attractive and challenging option. [9][10][11][12][13] These strategies can contribute to the goal of "defossilization" of the chemical value chain, in particular when combined with energy input from renewable resources.…”

“…With the growing emissions of greenhouse gases, the Earth's ecological systems are increasingly threatened . In recent decades, several nonbiological methods have been used for CO 2 capture, including physical adsorption, chemical absorption, and membrane separation . However, these methods are energy‐consuming and costly with a high environmental impact .…”

Carbonic anhydrase (CA) catalyzing CO 2 hydration has an important application in carbon capture, and its immobilization is very significant. Here, CA was covalently linked by glutaraldehyde (GA) to the surface of poly(vinylidene fluoride) (PVDF) and polyethylene (PE) membranes, which were previously modified via a simple codeposition of polyethyleneimine (PEI) and dopamine (DA). The effects of the modification conditions were investigated, and the membranes were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. The immobilization process was optimized, and the catalytic properties of immobilized CA were studied. The results show that the optimal mass ratio of PEI and DA was 1:1 and the deposition time was 10-12 h, at which the surface amino group density could reach 1.278 × 10 −7 and 1.397 × 10 −7 mol/cm 2 for PVDF and PE, respectively. For enzyme immobilization, the optimal CA and GA concentrations were 0.2 mg/mL and 0.1 wt %, and a maximum activity recovery of about 53% and 76% could be achieved for PVDF-attached CA and PE-attached CA, respectively. Their K m values were 10.62 mM and 8.6 mM, and the corresponding K cat /K m values were 132.2 M −1 s −1 and 312.9 M −1 s −1 . After immobilization, the storage stability and reusability of CA were much improved.

CO₂capture by amines in aqueous media and its subsequent conversion to formate with reusable ruthenium and iron catalysts

Abstract: Conversion of carbon dioxide (CO2) captured from industrial sources (e.g.flue gas of power plants) or even from ambient air to formate through CO2capture and utilization (CCU) as a possible strategy to mitigate anthropogenic CO2emissions to the atmosphere is proposed.
