The hydrogenation of furfural (FUR), a typical bio‐based furan derivative, is a critical reaction within the roadmap for upgrading lignocellulosic biomass into high value‐added chemicals and liquid fuels, the performance of which is strongly correlated with the catalysts’ intrinsic peculiarities. Metal catalysts with tailorable sizes, uniform dispersions and robust sintering resistance are generally recognized as a prerequisite for obtaining better hydrogenation activity, selectivity and stability, which has prompted intensive research into metal particle size effects and their regulation strategies. The roles of metal particle sizes and corresponding dispersions of metal catalysts used for FUR hydrogenation have been clearly recognized to be crucial over the past decade. In this regard, this systematic Minireview aims to provide profound insights into particle size effects in the metal‐catalyzed hydrogenation of FUR, as well as conditional and structural approaches to regulating these effects. In addition, from the aspect of catalyst stability, the impacts and improvements of the metal particle sintering issue are analyzed. Moreover, several suggestions are proposed in response to the challenges in regulating particle size effects. Furthermore, the viewpoints presented herein would potentially contribute to the rational development of metal hydrogenation catalysts and further help to boost a more sustainable biomass refining system.

生物质衍生糠醛的金属催化加氢:粒径效应和调控策略。

糠醛(FUR)(一种典型的生物基呋喃衍生物)的氢化是路线图中将木质纤维素生物质升级为高附加值化学品和液体燃料的关键反应,其性能与催化剂的固有特性密切相关。具有可定制的尺寸,均匀的分散性和强大的抗烧结性的金属催化剂通常被认为是获得更好的氢化活性,选择性和稳定性的先决条件,这促使人们深入研究金属粒度效应及其调节策略。在过去的十年中,已经清楚地认识到用于FUR加氢的金属粒径和金属催化剂的相应分散体的作用至关重要。在这方面,本系统的Minireview旨在深入探讨FUR在金属催化的FUR加氢中的粒径效应,以及调节这些效应的条件和结构方法。另外,从催化剂稳定性的角度,分析了金属颗粒烧结问题的影响和改进。此外,针对调节粒度效应的挑战提出了一些建议。此外,本文提出的观点将潜在地促进金属氢化催化剂的合理开发,并进一步帮助促进更可持续的生物质精制系统。分析了金属颗粒烧结问题的影响和改进。此外,针对调节粒度效应的挑战提出了一些建议。此外,本文提出的观点将潜在地促进金属氢化催化剂的合理开发,并进一步帮助促进更可持续的生物质精制系统。分析了金属颗粒烧结问题的影响和改进。此外,针对调节粒度效应的挑战提出了一些建议。此外,本文提出的观点将潜在地促进金属氢化催化剂的合理开发,并进一步帮助促进更可持续的生物质精制系统。
