A convenient and practical method for the preparation of precursors to form molybdenum carbide materials using solutions of ammonium heptamolybdate and sucrose is presented. Depending on the temperature-programmed reaction protocol employed [i.e., low temperature and long times (523K for 24h, 598K for 24h and 673K for 72h) or high temperature and short times (1073K for 30min)], the C/Mo ratio of the...
