Different hydrotalcites were synthesized by coprecipitation, replacing the Mg²⁺ ion by Cu, CuCo, and CuZn via two methodologies: at a constant pH of 10 and at changing pH. The solids were characterized by X-ray diffraction (XRD), thermogravimetry (TG), X-ray fluorescence (XRF) and temperature-programmed desorption (TPD). The activity of the solids as catalysts was evaluated by the hydrogenolysis of glycerol. The Co-containing catalysts had fewer acid sites, which possibly decreased the glycerol conversion. The CuZn catalyst prepared at constant pH was the most active under the conditions tested, achieving 38.56% conversion and 61.57% selectivity towards 1,2-propanediol.

通过共沉淀法合成了不同的水滑石，并通过两种方法将铜，铜钴和铜锌替换为Mg ²⁺离子：在恒定的pH 10和变化的pH下。通过X射线衍射（XRD），热重分析（TG），X射线荧光（XRF）和程序升温脱附（TPD）对固体进行表征。通过甘油的氢解评估了固体作为催化剂的活性。含Co的催化剂具有较少的酸位，这可能降低了甘油的转化率。在恒定pH下制备的Cu Zn催化剂在测试条件下活性最高，实现了38.56％的转化率和对1,2-丙二醇的选择性61.57％的选择性。
