By combining hydrogen evolution reaction (HER) with glycerol oxidation reaction (GOR), high-value chemicals can be obtained at the anode while saving energy to produce hydrogen. Herein, we synthesized Pt_SA-NiCo LDHs/NF by anchoring oxygen vacancies in NiCo LDHs with Pt to form Pt-O₅ coordination. Density functional theory (DFT) revealed that Pt_SA reduced the d-band center and optimized ΔG_H*. During HER, LDHs act as active sites to catalyze H-OH cleavage and promote the dissociation of H₂O, while Pt single atoms act as the binding sites for H intermediates, and Pt-O bonds accelerate proton-electron coupling and promote the release of H₂ molecules. In HER//GOR, a cell voltage of only 1.37 V is required to provide a current density of 100 mA cm⁻² and to produce formate at the anode. This work enables energy-saving hydrogen production and high-value chemicals at the anode, a novel green electrocatalytic synthesis strategy with synergistic coupling and dual promotion.

通过将析氢反应（HER）与甘油氧化反应（GOR）相结合，可以在阳极获得高价值的化学物质，同时节约能源制氢。在此，我们通过用 Pt 锚定 NiCo LDHs 中的氧空位形成 Pt-O _{5配位来合成 Pt SA} -NiCo LDHs/NF 。密度泛函理论 (DFT) 表明 Pt _SA降低了d带中心并优化了 ΔG _H*。在HER过程中，LDHs作为活性位点催化H-OH裂解，促进H ₂ O的解离，而Pt单原子作为H中间体的结合位点，Pt-O键加速质子-电子耦合并促进释放氢₂分子。在 HER//GOR 中，仅需要 1.37 V 的电池电压即可提供 100 mA cm ^-2的电流密度并在阳极产生甲酸盐。这项工作能够在阳极实现节能制氢和高价值化学品，这是一种具有协同耦合和双重促进作用的新型绿色电催化合成策略。
