Preparation of Cobalt Nitride from Co–Al Hydrotalcite and its Application in Hydrazine Decomposition

摘要

Alumina supported cobalt nitride [Co4N–Al2O3 (HT)] with high cobalt loading has been prepared for the first time from Co–Al hydrotalcite precursors. The formation of the Co4N phase was confirmed by XRD, H2-TPR, and XPS. Compared with Co4N/Al2O3 (IMP) prepared by conventional impregnation and nitriding, the hydrotalcite derived catalyst exhibited a much better activity for hydrazine decomposition as consequence of higher dispersion of active species.
