The development of functional nanodisperse materials based on porous template matrices is an urgent problem in the design of new devices in the processes of electrolysis of generation of "green" hydrogen, to increase energy saving of alternative energy sources, highly sensitive sensors for chemical technology, as new catalysts for afterburning automobile exhaust, in micro- and nanoelectronic devices. In this regard, the development of technology for the production of such materials, as well as studies of the relationship between the structure and catalytic properties of nanofilament matrix synthesis materials, seem relevant. A method of dynamic filtration of solutions using self-cleaning filters with continuous high-voltage processing of aluminum template matrices is proposed. Purification of aqueous solutions consists in the deposition of suspended aluminum salts on the working surface of titanium filters modified with an organofluorine component. The undoubted advantage of the proposed approach to the filtration process is the possibility of continuous removal of aluminum salt sediment from both the outer and inner surfaces of modified titanium filters due to a combination of cavitation created by built-in ultrasonic emitters and rotation of filter elements. The rotation of the filter elements allows you to direct the flow of liquid almost perpendicular to the flow passing through the filter. As a result, a tangential filtering mode is implemented, which prevents clogging of the filter. In addition, when the filter elements rotate, a partial transfer of torque to the liquid is carried out, due to which the liquid swirls around the filter elements. The swirling of the liquid causes a centrifugal effect of displacement of aluminum salts from the liquid layers adjacent to the filter elements, preventing clogging of the filter. The proposed filtration method for high-voltage electroplating of an aluminum matrix provides voltage and current density stabilization and the formation of ordered cylindrical nanoscale structures with a high aspect ratio.
