As a promising derivative to achieve efficient utilization of biomass, the preparation of 2,5-bis(hydroxymethyl)furan (BHMF) is of great significance. A kind of carbon nanotubes (CNTs)-supported metallic nickel and nickel oxide catalyst (Ni–NiO/CNTs) was prepared by an impregnation–reduction method and showed excellent catalytic activity in the catalytic transfer hydrogenation (CTH) of 5-hydroxymethylfurfural (HMF) to BHMF. Under optimal conditions, HMF conversion of 100% and BHMF selectivity of 97.6% were obtained using ethanol as the H-donor. Furthermore, it was found that Ni and NiO synergistically catalyzed the conversion of HMF into BHMF after the characterization of the catalyst and factor investigation. Significantly, the ratio of Ni to NiO on the catalyst surface played an important role in the high selectivity of BHMF. To establish the structure–activity correlation, a possible synergistic catalytic mechanism was proposed.

高效 Ni-NiO/碳纳米管催化剂用于 5-羟甲基糠醛选择性转移氢化成 2,5-双（羟甲基）呋喃

2,5-双(羟甲基)呋喃(BHMF)的制备作为一种有望实现生物质高效利用的衍生物,具有重要意义。采用浸渍-还原法制备了一种碳纳米管（CNTs）负载的金属镍和氧化镍催化剂（Ni-NiO/CNTs），在5-羟甲基糠醛（HMF）的催化转移加氢（CTH）中表现出优异的催化活性。 ) 到 BHMF。在最佳条件下，以乙醇为 H 供体，HMF 转化率为 100%，BHMF 选择性为 97.6%。此外，在对催化剂进行表征和因素研究后，发现 Ni 和 NiO 协同催化 HMF 向 BHMF 的转化。值得注意的是，催化剂表面 Ni 与 NiO 的比例对 BHMF 的高选择性起着重要作用。
