Here, the development of a new catalyst is reported for the selective furfural (FF) hydrogenation to furfuryl alcohol (FA) based on about 7 nm sized Pd−Cu alloy nanoparticles (NPs) formed in inexpensive, commercially available micro/mesoporous hypercrosslinked polystyrene (HPS). A comparison of the catalytic properties of as‐synthesized and reduced (denoted “r”) catalysts as well as Pd−Cu alloy and monometallic palladium NPs showed a considerable enhancement of the catalytic performance of Pd−Cu/HPS‐r compared to other catalysts studied, resulting in about 100 % FF conversion, 95.2 % selectivity for FA and a TOF of 1209 h⁻¹. This was attributed to the enrichment of the NP surface with copper atoms, disrupting the furan ring adsorption, and to the presence of both zerovalent and cationic palladium and copper species, resulting in optimal hydrogen and FF adsorption. These factors along with exceptional stability of the catalyst in ten consecutive catalytic cycles make it highly promising in practical applications.

生物质衍生糠醛的选择性加氢：多孔聚合物中Pd-Cu合金纳米颗粒的增强催化性能。

在这里，据报道开发了一种新的催化剂，用于将糠醛（FF）选择性氢化为糠醇（FA），该催化剂基于在便宜的市售微/中超交联聚苯乙烯中形成的约7 nm大小的Pd-Cu合金纳米颗粒（NP）（ HPS）。合成和还原（表示为“ r”）催化剂以及Pd-Cu合金和单金属钯NPs的催化性能比较表明，与其他催化剂相比，Pd-Cu / HPS-r的催化性能显着提高。研究表明，FF转化率约为100％，FA选择性为95.2％，TOF为1209 h ^-1。这归因于NP表面铜原子的富集，破坏了呋喃环的吸附，并且归因于零价和阳离子钯和铜物质的存在，从而导致了最佳的氢和FF吸附。这些因素以及催化剂在十个连续催化循环中的出色稳定性，使其在实际应用中前景广阔。
