Abstract

The glucose oxidation reaction (GOR) is a potential alternative to water oxidation because of its relatively low thermodynamic potential and the high availability of glucose. Herein, a FeCoO/N‐doped C electrode derived from metal–organic framework (MOF) materials is applied, which is synthesized in several steps through the controlled deposition of Fe–Co oxide nanocatalysts onto Co –N‐doped C nanofibers on a Ni foam substrate and demonstrate exceptional electrocatalytic activity for both the GOR and overall water splitting. Here, a bifunctional electrocatalyst derived from MOF, FeCoO/N‐doped C is reported, for glucose oxidation reaction (GOR) and hydrogen evolution reaction (HER). The MOF‐derived FeCoO/N‐doped C (+/‐) as a bifunctional electrocatalyst exhibits a cell voltage of 1.4 V for the GOR&HER, to reach a current density of 10 mA cm−2, which is 280 mV lower than that for the oxygen evolution reaction (OER)&HER (1.68 V). This study reveals that GOR is an energy‐efficient and affordable source of H2 and value‐added chemicals.

通过水和葡萄糖电解产生 H2 的 MOF 衍生 FeCoO/N 掺杂 C 双功能电极

葡萄糖氧化反应（GOR）是水氧化反应的一种潜在替代方法，因为它的热力学潜力相对较低，而且葡萄糖的可用性很高。本文应用了一种源自金属有机框架（MOF）材料的 FeCoO/N 掺杂 C 电极，该电极是通过在镍泡沫基底上的 Co -N 掺杂 C 纳米纤维上可控沉积 Fe-Co 氧化物纳米催化剂，分几步合成的。本文报告了一种源自 MOF、FeCoO/N-掺杂 C 的双功能电催化剂，用于葡萄糖氧化反应（GOR）和氢进化反应（HER）。由 MOF 衍生的 FeCoO/N-掺杂 C (+/-) 作为双功能电催化剂，在葡萄糖氧化反应 &HER 中的电池电压为 1.4 V，电流密度为 10 mA cm-2，比氧进化反应 (OER)&HER 的电池电压（1.68 V）低 280 mV。这项研究表明，GOR 是一种高效节能且经济实惠的 H2 和增值化学品来源。
