β¦ Synopsis
Nitrkled 11.7% and 97.1 % molybdena-alumina catalysts have been investigated using temperature-programmed reaction with hydrogen (TPR) and diffuse reflectance FTlR connected toa mass spectrometer with the aid of XRD analysis.
From the TPR and XRD analyses, y-Mo2N was formed on the surface of the 1 1.7% and 97.1 % Mo/A1203 nitrided at 700Β°C.
On the basis of the NH3-TPD and IR spectroscoples, much more Lewis acid sites than Bransted acid sites are present on the surface of the nitrided molybdena-alumina.
