The production of Cu/Ag nano-bimetals for the CO₂ reduction on a catalytically active cathode is studied according to the following scheme: the formation of porous copper as a result of selective anodic dezincification of Cu–Zn alloy in an H₂SO₄ solution and deposition of silver nanostructures by the galvanic replacement. It is shown that the nanosized dendritic formations of silver (70–100 nm) are deposited on the surface of nanoporous copper in a 0.01 M AgNO₃ solution in the ultrasound field. It is shown that the main factor of influence on the morphology of the reduced silver on porous copper is the duration of the galvanic replacement. It is also demonstrated that the electrodes with porous Cu/Ag nanosurfaces are characterized by a much higher catalytic activity as compared with brass foil and porous copper.

根据以下方案研究了用于在催化活性阴极上还原CO ₂的 Cu/Ag 纳米双金属的生产：由于 Cu-Zn 合金在 H ₂ SO ₄中选择性阳极脱锌而形成多孔铜通过电流置换解决和沉积银纳米结构。结果表明，在 0.01 M AgNO _{3 中}，银的纳米级树枝状结构（70-100 nm）沉积在纳米多孔铜的表面上超声领域的解决方案。结果表明，影响多孔铜上还原银形态的主要因素是电置换的持续时间。还表明，与黄铜箔和多孔铜相比，具有多孔 Cu/Ag 纳米表面的电极具有更高的催化活性。
