摘要
在寻找高效、经济的催化剂来推动电化学水分离过程中的氢进化反应(HER)时,泡沫铜(CuF)是电极涂层的理想候选材料。贵金属催化剂(如 Pt/C)在这一领域占主导地位,但由于其成本高且稀缺,必须加以改进。因此,我们合成并评估了一系列镍源电催化剂(镍、镍钼、镍磷和镍钼磷),并通过电沉积 CuF 促进 HER 性能的大幅提高。其中,Ni-Mo-P 三元体系因其理想的电子结构和催化机制,有助于提高 HER 的热力学和动力学性能。性能分析表明,所有研究的催化剂在塔菲尔斜率和过电位方面都遵循 Ni/CuF > NiMo/CuF > NiP/CuF > NiMoP/CuF 的顺序。因此,表现最出色的 NiMoP/CuF 在水分裂过程中表现出卓越的热力学性能,在 1.0 M KOH 条件下,η10 = 159 mV,塔菲尔斜率动力学值为 126.66 mV-dec-1。总之,本报告提出了一种优化 CuF 电涂层催化剂在 HER 中的电催化功能和稳定性的有效方法。这项研究为开发具有成本效益、稳定和高效的 HER 催化剂开辟了新途径,展示了 NiMoP/CuF 在推进可持续制氢技术方面的潜力。
Electrodeposition of Nickel–Molybdenum–Phosphide on copper foam electrode for efficient hydrogen evolution reaction
In the quest for efficient and cost-effective catalysts to drive the hydrogen evolution reaction (HER) in electrochemical water splitting, copper foam (CuF) is a favorable candidate for electrode coating. Precious metal catalysts like Pt/C dominate the field but must be improved because of their high cost and scarcity. Therefore, we have synthesized and evaluated a sequence of nickel-originated electrocatalysts (Ni, NiMo, NiP, and NiMoP) with the electrodeposition of CuF to facilitate substantial improvements in HER performance. Herein, the Ni–Mo–P ternary system, owing to its desirable electronic structure and catalytic mechanism, contributes to enhancing the thermodynamics and kinetics of the HER. Performance analysis reveals that all studied catalysts follow the order of Ni/CuF > NiMo/CuF > NiP/CuF > NiMoP/CuF regarding both the Tafel slope and overpotential. Hence, the top performer, NiMoP/CuF, exhibits tremendous thermodynamics with an η10 = 159 mV and Tafel slope kinetics of 126.66 mV·dec⁻1 at 1.0 M KOH in water splitting. Overall, this report presents a well-capable way of optimizing the electrocatalytic function and stability of CuF-electro-coated catalysts for the HER. This research opens new avenues for cost-effective, stable, and efficient HER catalysts, showcasing the potential of NiMoP/CuF in advancing sustainable hydrogen production technologies.
