Abstract

The selective conversion of furfural is the key to the synthesis of bio-based fine chemicals, but it is still challenging due to the complexity of multi-pathway reactions. Herein, MOFs-derived 3D Cu@CN framework with layered structure were constructed via a dual-linkers strategy. The prepared Cu@CN-400 has good catalytic performance, the yield of furfuryl alcohol is more than 99%, and the catalyst can still maintain high activity after 10 cycles. The characterization and experimental results confirm that this strategy benefits the catalyst in two aspects, namely, the generation of a certain proportion of exposed Cu0 species and the formation of a layered structure with Cu embedded in nitrogen-doped carbon. The first aspect improves the activity of the catalyst, while the second aspect greatly inhibits the leaching of metal components during the reaction, thereby ensuring the stability of the catalyst. This study provides a feasible strategy for designing stable catalysts to achieve highly selective conversion of furfural.

原位生成三维Cu@CN糠醛选择性合成糠醇骨架催化剂
糠醛的选择性转化是生物基精细化学品合成的关键,但由于多途径反应的复杂性,其选择性转化仍具有挑战性。在此基础上,通过双链接策略构建了具有分层结构的mofs衍生3D Cu@CN框架。所制备的Cu@CN-400具有良好的催化性能,糠醇收率达99%以上,催化剂经过10次循环后仍能保持高活性。表征和实验结果证实,该策略在两个方面有利于催化剂,即产生一定比例的暴露Cu0物种和形成层状结构,Cu嵌入氮掺杂碳中。第一方面提高了催化剂的活性,而第二方面则大大抑制了反应过程中金属组分的浸出,从而保证了催化剂的稳定性。本研究为设计稳定的糠醛高选择性转化催化剂提供了可行的策略。图形抽象
