Ni–Mo–N precursor was synthesized via a complexation reaction using nickel acetate, ammonium molybdate and hexamethylenetetramine (HMT) as starting materials and then heat-treated at high temperature in hydrogen atmosphere to obtain the final catalyst. The effects of preparation conditions such as Ni/Mo molar ratio and treatment temperature on the catalytic hydrodeoxygenation (HDO) activity were studied by taking acetophenone as a carboxide in bio-oil. 100% Conversion with a 99.1% selectivity of ethylbenzene was achieved after reaction at 150 °C for 1 h. The deoxygenation degree was further enhanced by increasing the reaction temperature and hydrogen pressure. The high activity of Ni–Mo–N catalyst was attributed to the formation of Ni₂Mo₃N phase. During the reusability test, acetophenone conversion on Ni–Mo–N catalyst was almost unchanged, but the deoxygenation degree was slightly lowered with the increase of recycle number, which was mainly caused by the nitrogen loss.

通过使用乙酸镍，钼酸铵和六亚甲基四胺（HMT）作为起始原料，通过络合反应合成Ni-Mo-N前驱物，然后在氢气氛围中于高温下进行热处理，以得到最终的催化剂。以苯乙酮为生物油中的一种碳氧化物，研究了Ni / Mo摩尔比和处理温度等制备条件对催化加氢脱氧反应（HDO）活性的影响。在150°C下反应1小时后，乙苯的转化率为100％，转化率为99.1％。通过提高反应温度和氢气压力进一步提高了脱氧度。Ni-Mo-N催化剂的高活性归因于Ni ₂ Mo ₃的形成N相。在可重复使用性测试中，Ni-Mo-N催化剂上的苯乙酮转化率几乎没有变化，但随着循环次数的增加，脱氧度略有降低，这主要是由于氮的流失所致。
