Abstract

It is significant that electrocatalytic water splitting for hydrogen evolution reaction (HER) and 5-hydroxymethylfurfural (HMF) is oxidized as 2,5-furandicarboxylic acid (FDCA). Herein, the monocrystal NiSbSn_0.5O_4.5 MEAO was synthesized, which shows good HMF oxidative reaction (HMFOR) sensitivity that the HMFOR potential is only 1.51 V at 10 mA cm⁻², and the HMF is converted to FDCA with the Faradaic efficiency (FE) of 85.3 % at 1.2 V. Besides, the NiSbSn_0.5O_4.5 shows a low HER overpotential of 229 mV at 10 mA cm⁻² in 1 M KOH + 0.1 M HMF, and the cell voltage is as low as 0.70 V at 10 mA cm⁻². This work provides a potential avenue to design a ternary MEAO for electrocatalytic HER and HMFOR.

用于氢气进化和 5-羟甲基糠醛氧化的 NiSbSn0.5O4.5 中熵合金氧化技术

电催化水分裂进行氢进化反应（HER），5-羟甲基糠醛（HMF）被氧化为2,5-呋喃二甲酸（FDCA），这一点意义重大。本文合成了单晶 NiSbSn0.5O4.5 MEAO，它具有良好的 HMF 氧化反应（HMFOR）灵敏度，在 10 mA cm-2 时 HMFOR 电位仅为 1.51 V，HMF 转化为 FDCA 的法拉第效率（FE）为 85.此外，NiSbSn0.5O4.5 在 1 M KOH + 0.1 M HMF 中显示出较低的 HER 过电位，10 mA cm-2 时为 229 mV，10 mA cm-2 时电池电压低至 0.70 V。这项工作为设计用于电催化 HER 和 HMFOR 的三元 MEAO 提供了一条潜在的途径。
