Cu(II)Cu(I)/activated carbon (AC) catalysts with different copper chloride and cuprous chloride impregnation orders were prepared. The effect of the Cu(II) additive on the catalytic performance of Cu(I)/AC catalysts for gas–solid acetylene dimerization was evaluated. The optimal catalytic performance was obtained using the Cu(II)0.3Cu(I)1/AC catalyst with an average acetylene conversion of 70.0%. This value was an increase of 33.0% compared to the average acetylene conversion of 37.0% (Cu(I)1/AC) under the same reaction conditions. The results from the characterization of the Cu(II)Cu(I)/AC catalysts demonstrated that the addition of Cu(II) increased the dispersion of copper and inhibited copper loss on the catalysts. Consequently, our findings indicate that a suitable Cu⁺/Cu²⁺ molar ratio improves the catalytic performance and stability.

Cu（II）Cu（I）/ AC催化剂，用于气固乙炔二聚

制备了具有不同氯化铜和氯化亚铜浸渍顺序的Cu（II）Cu（I）/活性炭（AC）催化剂。评估了Cu（II）添加剂对Cu（I）/ AC催化剂对气固乙炔二聚反应催化性能的影响。使用具有平均乙炔转化率为70.0％的Cu（II）0.3Cu（I）1 / AC催化剂可获得最佳催化性能。与相同反应条件下的平均乙炔转化率37.0％（Cu（I）1 / AC）相比，该值增加了33.0％。Cu（II）Cu（I）/ AC催化剂的表征结果表明，添加Cu（II）可以提高铜的分散性并抑制催化剂上的铜损失。因此，我们的发现表明合适的Cu ⁺ / Cu ²⁺ 摩尔比提高了催化性能和稳定性。
