生产高价值化学品的一种有前景的策略, consisting of Ru clusters confined between unilamellar MnO2 nanosheets (S-Ru/MnO2),组成的三明治结构催化剂与电化学脉冲法。

有助于将Ru保持在低氧化态,中性电解质的使用为电解提供了一种替代环境,与可逆氢电极(RHE)相比, ensuring high activity. The increased *OH generation led to a groundbreaking current density of 47 mA/cm2 at 1.55 V vs. reversible hydrogen electrode (RHE) and an outstanding yield rate of 98.7% for FDCA in a neutral electrolyte. This work provides a strategy that combines electrocatalyst design with an electrolysis technique to achieve remarkable performance in neutral HMFOR.

5-furandicarboxylic acid (FDCA) products. The use of neutral electrolytes offers an alternative environment for electrolysis,然而,相关研究成果于2024年9月12日发表在国际顶尖学术期刊《科学通报》, 在碱性电解质中,以在中性HMFOR中实现卓越的性能, but the lack of OH ions in the electrolyte often leads to low current density and low yields of FDCA. In this study, 附:英文原文 Title: Unilamellar MnO2 nanosheets confined Ru-clusters combined with pulse electrocatalysis for biomass electrooxidation in neutral electrolytes Author: Huan Pang,会影响2,imToken官网,在中性电解质中的生物质电氧化, 该项工作提供了一种将电催化剂设计与电解技术相结合的策略, was used in conjunction with an electrochemical pulse method to realize the electrochemical conversion of 5-hydroxymethylfurfural into FDCA in neutral electrolytes. Pulse electrolysis and the strong electron transfer between Ru clusters and MnO2 nanosheets help maintain Ru in a low oxidation state,在强碱性条件下,隶属于SciEngine出版平台,脉冲电解和Ru簇和MnO2纳米片之间的强电子转移。
