METHODS FOR SELECTIVELY DEPOSITING NANO- OR MICROSCOPIC PLUGS IN MEMBRANES FOR ELECTROCHEMICAL APPLICATIONS

Resumen de: US20260275551A1

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.
