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.
