摘要

用浸渍-燃烧法制备了固体超强碱MgO-CaO和MgO-SrO负载的高分散铜基催化剂

并将其用于甘油氢解制备1

2-丙二醇的反应。N2吸附、X射线衍射、透射电子显微镜、H2程序升温还原和N2O氧化吸附及CO2程序升温脱附等表征实验结果显示:Cu粒子均分散于Cu/MgO-CaO(或者Cu/MgO-SrO)催化剂的表面;与Cu/MgO相比

Cu/MgO-CaO和Cu/MgO-SrO具有更强的碱性

可以加速甘油的转化。上述结果表明

甘油氢解反应中铜催化剂的活性随碱性的增强而增加。

Abstract

Highly dispersed copper nanoparticles supported on combined alkaline-earth metal oxides MgO-CaO and MgO-SrO were synthesized by impregnation-combustion method and used for hydrogenolysis of glycerol. The nanoparticles were characterized using N2-adsorption

X-ray diffraction

transmission electronic microscope

temperature-programmed reduction with H2

dissociative N2O adsorption and CO2 temperature-programmed desorption. The results revealed that Cu particles dispersed highly on the surface of Cu/MgO-CaO and Cu/MgO-SrO catalyst. The enhanced alkalinity of Cu/MgO-CaO and Cu/MgO-SrO accelerated the conversion of glycerol compared to Cu/MgO. It was concluded that the activity of Cu-based catalyst increased with its alkalinity.
