Abstract

In this report, several series of AB₂O₄ (A = Zn²⁺ (Cu²⁺); B = Al³⁺, Cr³⁺) nanospinels were synthesized by hydrothermal method at different hydrothermal temperatures in autoclave. In this synthesis, the thermodifferential analysis method was used to find out the optimum temperature of calcinations for nanospinel phase formation. The structural, textural properties of the catalysts as-obtained were characterized by physical methods: DTA-TGA, XRD, TEM, BET. Their catalytic activity was measured by using oxidative dehydrogenation reaction of ethylbenzene to styrene at different temperatures. From experiment results obtained, it is observed that in the presence of the nanospinels catalysts, the catalytic activity and selectivity in styrene is high. [DOI: 10.1380/ejssnt.2012.268]
