The dehydrogenation of 2,3-butanediol (BDO) to 3-hydroxybutanone (HBO) was studies over Li cation-doped CuZnAl catalysts. The catalyst samples were characterized by XRD, XPS, H₂-TPR and SEM techniques. The characterization results showing that doping with Li cation obviously modified the surface morphology of CuZnAl catalysts; decreased the reduction temperature of CuZnAl catalysts; and finally increased the amount of Cu active sites. The reaction results showing that, Li modified CuZnAl catalysts obviously enhanced the selectivity of the dehydrogenation of BDO to HBO by inhibiting the dehydration of BDO. The Li(2%)–Cu(44%)–Zn(38%)–Al(16%) exhibited the highest activity for dehydrogenation of BDO, with the conversion rate of BDO is 72.4% and the selectivity of HBO is 95.9% at 260 °C. This catalyst shows excellent stability for more than 100 h without significant deactivation.

在掺杂锂阳离子的CuZnAl催化剂上研究了2,3-丁二醇（BDO）脱氢成3-羟基丁酮（HBO）。催化剂样品通过XRD，XPS，H ₂表征-TPR和SEM技术。表征结果表明，掺杂Li阳离子明显改变了CuZnAl催化剂的表面形貌。降低了CuZnAl催化剂的还原温度；最终增加了铜的活性位。反应结果表明，Li改性的CuZnAl催化剂通过抑制BDO的脱水，明显提高了BDO脱氢为HBO的选择性。Li（2％）– Cu（44％）– Zn（38％）– Al（16％）表现出最高的BDO脱氢活性，BDO的转化率为72.4％，HBO的选择性为95.9％在260°C下。该催化剂在超过100小时的时间内表现出出色的稳定性，并且没有明显的失活。
