Highly active and selective supported bulk nanostructured MoVNbTeO catalysts for the propane ammoxidation process

摘要: Abstract We report a methodology to prepare nanoscaled supported-bulk MoVNbTeO catalysts in which the phases required obtain an active and selective are on surface of support. Thus, more economic catalytic material with improved mechanical properties can be obtained. The effect vanadium content atmosphere calcination performance discussed, results supported-catalysts compared those bulk samples, have been prepared as reference. best supported catalyst afford ca. 50% acrylonitrile yield 80% propane conversion at 450 °C. activity per gram increases fourfold upon stabilization its nanoparticles.
