Abstract

Electrocatalytic glucose oxidation reaction (GOR) to produce high value-added chemicals is facilitating the selective conversion and efficient utilization of biomass, while the oxidation products and reaction pathways associated with different transition metals remain insufficiently explored. Herein, the GOR performance on Co, Ni, and Cu metal aerogels were systematically investigated, exhibiting the activity order of Ni > Co > Cu for GOR electrocatalysis. Metal oxyhydroxides (M-OOH) from surface reconstruction of metal aerogels are identified as the actual active species, and the glucose adsorption strength on M-OOH correlated to the GOR property for metal aerogels are elucidated. In situ characterizations further revealed the interfacial reaction mechanism and reaction path on Ni aerogel with high activity and formic acid selectivity. Besides, the efficient GOR property of Ni aerogel further promoted stable water electrolysis at high current densities. Thus, this study offers constructive guidance for designing high-performance GOR electrocatalysts and establishes a feasible prototype for biomass upgradation.

过渡金属气凝胶吸附介导的高效葡萄糖电氧化用于生物质升级

电催化葡萄糖氧化反应（GOR）生产高附加值化学品促进了生物质的选择性转化和高效利用，而与不同过渡金属相关的氧化产物和反应途径尚未得到充分探索。本文系统地研究了Co、Ni和Cu金属气凝胶上的GOR性能，展示了Ni >； Co >； Cu对GOR电催化的活性顺序。从金属气凝胶的表面重构中确定了金属氢氧化物（M-OOH）为实际活性物质，并阐明了M-OOH对葡萄糖的吸附强度与金属气凝胶GOR性能的关系。原位表征进一步揭示了高活性和甲酸选择性Ni气凝胶的界面反应机理和反应路径。此外，Ni气凝胶的高效GOR特性进一步促进了高电流密度下的稳定水电解。因此，本研究为高性能GOR电催化剂的设计提供了建设性的指导，并为生物质升级建立了可行的原型。

期刊介绍： Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
