On the nature of active sites in MoVTeO and MoVTeNbO catalysts: The influence of catalyst activation temperature

MoVTeO and MoVTeNbO catalysts, prepared hydrothermally and heat-treated at 500, 550 or 600 °C in a N 2 atmosphere, have been characterized and tested in the partial oxidation of propane to acrylic acid. The heat-treatment has different influence on the formation and stability of M1, the surface char...
