Cu2O@TiO2 core-shell microspheres for naphthalene oxidation

New Cu2O@TiO2 core-shell microspheres were successfully prepared for the first time in this paper. The XRD, N2 adsorption-desorption, SEM, TEM, EDX and XPS characterizations utilized to investigate physical chemical properties. liquid phase oxidation of naphthalene was also carried out test their catalytic performance. characterization results indicating that Cu2O firstly formed by hydrothermal treatment rutile TiO2 coating on surface would be hydrolysis tetrabutyl titanate. [email protected] catalyst with molar ratio copper titanium species as high 5.0 has largest area maximum pore volume resulting from integrated rougher thickness about 6.3 nm, it showed higher performance naphthalene. Naphthalene conversion 43.2%, 1, 4-naphthoquinone selectivity 26.7% phthalic anhydride 53.4% can obtained, only slightly decreased even after repeated use 5 times. method provide a valuable theoretic reference hindrance rapid deactivation industrial application produce chemicals.
