Nanoporous Ni (NP-Ni) and NiMnO2 (NP- NiMnO2) were prepared with mechanical alloying method and compared for the hydrodeoxygenation (HDO) of guaiacol. It was shown that MnO2 as an additive has a significant influence on the catalytic performance as it could accordingly change the material properties. Results of characterization demonstrated that NP-NiMnO2 had a unique structure with higher degree of amorphization than NP-Ni, which significantly facilitated the activity of HDO. Under the optimal reaction conditions of 150 °C and 0.5 MPa of H2 pressure, guaiacol was completely converted into cyclohexanol with 95.6% selectivity and NP-NiMnO2 was recycled 6 times without obvious deactivation.

促进非晶态纳米多孔NiMnO 2上愈创木酚的选择性加氢脱氧
采用机械合金化法制备了纳米多孔Ni(NP-Ni)和NiMnO 2(NP- NiMnO 2),并对愈创木酚的加氢脱氧(HDO)进行了比较。结果表明,MnO 2作为添加剂对催化性能有重要影响,因为它可以相应地改变材料性能。表征结果表明,NP-NiMnO 2具有比NP-Ni更高的无定形度的独特结构,从而显着促进了HDO的活性。在150°C和0.5 MPa H 2压力的最佳反应条件下,愈创木酚被完全转化为环己醇,选择性为95.6%,NP-NiMnO 2 回收了6次,没有明显失活。
