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.

The efficient separation of photogenerated electron–hole pairs is a critical challenge that hampers the performance photocatalytic systems. In this work, NiCo2S4/ZnCdS (NiCo2S4/ZCS) Schottky junction was constructed by simple physical mixing method. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results proved NiCo2S4 an amorphous material, density functional theory (DFT) calculations confirmed metallic nature NiCo2S4. light absorption capacity NiCo2S4/ZCS heterojunction significantly enhanced with loading. formation junctions between ZnCdS in transfer spatial prevents recombination charge carriers. Therefore, optimized 20% exhibits remarkable hydrogen evolution (PHE) activity 25 mmol g–1 h–1, which 4.79 150.6 times higher than alone This work provides successful strategy for preparing ZnCdS-based to promote PHE activity.
