A cyclic process for the capture of carbon dioxide (CO2) directly from air utilizing a three-compartment electrolytic cell coupled with a hydroxide-based CO2 capture system as well as a carbonate-based CO2 capture system. Air is passed over a hydroxide compound in the hydroxide-based CO2 capture system to extract carbon dioxide from the air and produce a carbonate compound which is transferred to the carbonate-based CO2 capture system, where air is passed over the carbonate compound to extract carbon dioxide from the air and produce a bicarbonate compound. The bicarbonate is then passed into the three-compartment electrolytic cell where CO2, hydrogen and oxygen gases are separately released and the bicarbonate solution is transformed into a hydroxide solution that is reused in the hydroxide-based CO2 capture system. The flow of input compounds from one system to the other enables efficient operation of the direct air capture of carbon dioxide system.

Crossover through submicron thick SiO2 membranes can be mitigated by selectively depositing oxide, e.g., carbon-containing silicon oxide (SiOxCy) “nanoplugs” into the pinholes and cracks of the membranes. Defect-containing membranes are contacted with a deposition solution including hydrolysable precursors, e.g., metal alkoxides like tetraethyl orthosilicate (TEOS), and a nanoplug directing agent, e.g., tetramethylammonium bromide (TMAB). Current is applied to the defect-containing membranes in pulses, including a shorter “on” phase where current is applied and a longer “off phase” where current is not applied. The SiOxCy nanoplugs are deposited to the structural defects during the “on” phase. The longer “off phase” enables reactants to diffuse back to the structural defects for deposition of additional nanoplugs during the next “on” phase, as well as prevent deposition of SiOxCy on non-defective regions. Treatment of plugged SiO2 membranes reduced H2 permeation rates by 5-6 orders of magnitude compared to unmodified SiO2 and 1-2 orders of magnitude compared to Nafion-117 membranes.

An electrochemical system produces a gas from an aqueous solution. A liquid is circulated from a half-cell to a reaction vessel and then returned to the half-cell. A redox mediator in the liquid is converted from a first state to a second state in the half-cell and reacts to form a gas in the reaction chamber while being returned to its first state. The circulating liquid also includes a high molecular weight linear polymer or a viscoelastic surfactant which forms wormlike micelles enabling it to be in a state of elastic turbulence and the reaction chamber is configured to compel changes of flow direction so that the liquid is in a state of elastic turbulence as it flows through the reaction chamber. The half-cell may be configured such that the liquid is in a state of elastic turbulence as it flows through the half-cell.
