Abstract

Inexpensive hierarchically hortensia-like α-Ni(OH)₂ catalysts without prereduction were introduced to the 5-hydroxymethylfurfural (HMF) hydrogenation to 2,5-bis(hydroxymethyl)furan (BHMF) via the catalytic transfer hydrogenation (CTH) process. Given the catalytic performance evaluated on the hortensia-like α-Ni(OH)₂, the catalyst of Ni(OH)₂-OLA synthesized using an oleylamine-assisted solvothermal method has prospective in the HMF hydrogenation to BHMF. A remarkable 95.96% of the BHMF selectivity with 96.81% of the HMF conversion was obtained on Ni(OH)₂-OLA at 135°C for 5 h under N₂ atmosphere using the ethanol as the hydrogen donor. Based on the kinetic analysis, the lowest activation energy of 39.6 kJ·mol⁻¹ and the highest preexponential factor of 19.1 s⁻¹ could be found on Ni(OH)₂-OLA, which revealed the superior catalytic performance in the HMF hydrogenation to BHMF over Ni(OH)₂-OLA. Moreover, excellent stability and reusability also could be found on Ni(OH)₂-OLA, which indicated that the hortensia-like α-Ni(OH)₂ catalysts have the potential for industrialization. The findings of this study provide an efficient catalyst system with low-cost and high-performance for the HMF hydrogenation via the CTH process.

α-Ni(OH)2催化生物质衍生5-羟甲基糠醛转化为2,5-双（羟甲基）呋喃的研究

通过催化转移加氢（CTH）工艺，将价格低廉、结构类似hortensia的α-Ni(OH)2催化剂引入5-羟甲基糠醛（HMF）加氢制备2,5-二（羟甲基）呋喃（BHMF）。通过对类霍顿西亚α-Ni(OH)2的催化性能的评价，表明采用油胺辅助溶剂热法合成的Ni(OH)2- ola催化剂在HMF加氢制BHMF中具有应用前景。在Ni(OH)2-OLA上，以乙醇为供氢剂，在135℃、N2气氛下反应5 h，获得了95.96%的选择性和96.81%的HMF转化率。动力学分析表明，Ni(OH)2-OLA的最低活化能为39.6 kJ·mol−1，指数前因子最高为19.1 s−1，表明Ni(OH)2-OLA催化HMF加氢制BHMF的性能优于Ni(OH)2-OLA。此外，Ni(OH)2- ola催化剂还具有良好的稳定性和可重复使用性，表明类霍顿西亚α-Ni(OH)2催化剂具有产业化潜力。本研究结果为甲基糠醛CTH加氢提供了一种低成本、高性能的催化剂体系。

期刊介绍： As the leading archival journal devoted exclusively to chemical kinetics, the International Journal of Chemical Kinetics publishes original research in gas phase, condensed phase, and polymer reaction kinetics, as well as biochemical and surface kinetics. The Journal seeks to be the primary archive for careful experimental measurements of reaction kinetics, in both simple and complex systems. The Journal also presents new developments in applied theoretical kinetics and publishes large kinetic models, and the algorithms and estimates used in these models. These include methods for handling the large reaction networks important in biochemistry, catalysis, and free radical chemistry. In addition, the Journal explores such topics as the quantitative relationships between molecular structure and chemical reactivity, organic/inorganic chemistry and reaction mechanisms, and the reactive chemistry at interfaces.
