for biomass valorization is a highly attractive topic. Herein, we conducted the first work on electrocatalytic oxidation of renewable furfural to produce the key bioactive intermediate 5-hydroxy-2(5H)-furanone (HFO). It was demonstrated that using H2O as the oxygen source and metal chalcogenides (CuS, ZnS, PbS, etc.) as electrocatalysts, the reaction could proceed efficiently, and the CuS nanosheets prepared
开发有效的生物质增值策略是一个非常有吸引力的话题。在这里,我们进行了可再生糠醛的电催化氧化的第一项工作,以生产关键的生物活性中间体5-羟基-2(5 H)-呋喃酮(HFO)。结果表明,使用H 2 O作为氧源,并使用金属硫属化物(CuS,ZnS,PbS等)作为电催化剂,反应可以高效进行,并且本工作制备的CuS纳米片表现出最佳性能并提供了高HFO糠醛的选择性(83.6%)和高转化率(70.2%)。另外,CuS电催化剂显示出长期稳定性。机理研究表明糠醛通过 多步反应,包括C–C裂解,随后的开环和氧化以及分子内异构化。
