使用 TiO2 负载的 2 wt% Pd 和 2 wt% Pd–x wt% Re 催化剂，采用浸渍法或单金属催化剂的表面氧化还原还原，对琥珀酸水溶液进行氢化。前者的催化剂在活性和对1,4-丁二醇的选择性方面优于后者。然而，需要更高的铼负载量（3.4-3.6 wt% 与 0.6-0.8 wt% 相比）才能启动这种协同作用。
Hydrogenation of succinic acid aqueous solutions was performed using TiO2-supported 2 wt% Pd and 2 wt%Pd–x wt%Re catalysts, using either impregnation method or surface redox reduction of the monometallic catalyst. The former catalysts were superior in terms of activity and selectivity to 1,4-butanediol than the latter ones. However, higher Re loadings (3.4–3.6 wt% compared to 0.6–0.8 wt%) were necessary to initiate this synergy.
