Catalytic Oxidation of n-Butanol over Mg4Ce2 Hydrothalcite based System: Effect of Water Vapor and Volatile Organic Compounds Mixture

This study investigates Mg4Ce2 layered double hydroxides (LDH), focusing on its structural and catalytic properties.  The sample was characterized by XRD, BET, Raman, XPS, and DTA/TGA techniques. Its performance in the oxidation of n-butanol, including the influence of water vapor and the presence of ethyl acetate was studied. Results show promising catalytic activity of Mg4Ce2 hydrotalcite, with total butanol conversion achieved at 250°C. However, the presence of water vapor and the coexistence of ethyl acetate and butanol lead to slight decreases in catalytic efficiency, with a more pronounced inhibitory effect observed when both compounds are present together.
