摘要

在丙酮和正丁醇的连续气相醛醇缩合反应中,研究了在不同温度下制备的铜、银和银铜结合热处理氢铝酸盐催化剂的催化活性/选择性。通过气体吸附分析、X 射线衍射 (XRD)、紫外可见光漫反射光谱 (DR-UV)、氢气温度编程还原 (H2-TPR)、二氧化碳温度编程解吸 (CO2-TPD) 和扫描电子显微镜与能量色散光谱 (SEM/EDS),对合成的催化剂进行了表征。交叉和自醛缩合反应产生了多种缩合产物的混合物。在热处理氢铝酸盐中掺入铜、银和银铜可提高碳原子数为 11(C11)的化合物的催化活性和选择性,尤其是在 800 °C 下掺入银铜的热处理氢铝酸盐催化剂(AgCu/HT800)上。

Catalytic conversion of acetone and n-butanol over metal incorporated hydrotalcite-derived oxides catalysts

The catalytic activity/selectivity of copper, silver, and silver-copper incorporated thermally treated hydrotalcite catalysts prepared at different temperatures were investigated in the continuous gas phase aldol condensation reaction between acetone and n-butanol. The synthesized catalysts were characterized by gas adsorption analysis, X-ray diffraction (XRD), ultraviolet–visible diffuse reflectance spectroscopy (DR-UV), temperature-programmed reduction with hydrogen (H2-TPR), temperature-programmed desorption of carbon dioxide (CO2-TPD) and scanning electron microscopy with energy dispersive spectroscopy (SEM/EDS). A mixture of several condensation products was produced by the cross- and self-aldol condensation reactions. Incorporation of copper, silver and silver-copper into thermally treated hydrotalcite can enhance the catalytic activity and selectivity of compounds with carbon number 11 (C11), especially over silver-copper incorporated thermally treated hydrotalcite catalysts at 800 °C (AgCu/HT800).

期刊介绍: The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
