Green hydrogen production technology is an effective strategy for solving energy problems and environmental issues. In this paper, we report a bipolar system: Au–CuxO/CF∥Ru–CuxO/CF, in which the cathode produces through evolution reaction (HER) process anode formaldehyde oxidation (FOR). It found that when Au–CuxO/CF used FOR, C–H bond of will be broken at low potential to produce reactive H*. H* recombined Tafel step (H* + ⇌ H2) H2. At same time, oxidized high-value-added product HCOOH. We formation grain boundary-rich structures on Au–CuxO surface jointly promotes potentials. addition, introduced Ru elements into CuxO enhance cathodic HER. The FOR-HER system Au–CuxO/CF∥Ru–CuxO/CF was tested flow cell. produced current density 500 mA cm–2 only 0.38 V. This work provides construction catalyst design ideas voltages.
