Abstract
In the present paper the effect of the MoO3 precursor and procedure on the synthesis of beta-phase molybdenum nitride is reported. Two different sources of MoO3 were used, and treated under a flow of gas N2/H2 at 700 or 750 °C employing various heating ramp rates. All samples were characterized by XRD, SEM and their textural properties were determined by application of the BET method. The results show that, depending on the precursor, markedly different morphologies were observed, whereas both the molybdenum source and the thermal treatment, strongly influence the incorporation of nitrogen.
