“…The Mo centers in the complex catalysts are typically coordinated with a bulky ligand to stabilize the Mo complex. [38][39][40][41][42][43][44] Non-green reductants such as PPh 3 and metallic Al were used in these studies. The reported yields by the Mo complex catalysts were not high in comparison with the systems using homogeneous Re catalysts with the same reductants.…”

A strategy is proposed to enhance the stability and reusability of the ReOx‐Pd/CeO2 catalyst for the consecutive deoxydehydration and hydrogenation (DODH + HG) of biomass‐derived vicinal diols. A remarkable result involving a simultaneous enhancement of activity, stability, and regeneration ability of the catalyst is obtained by lowering the surface concentration of metals. Using erythritol as a model compound, DODH + HG over a low‐loading ReOx‐Pd/CeO2 can be completed much faster with a higher turnover number compared to the high‐loading standard catalyst. Moreover, a three‐fold decrease in deactivation rate is also obtained when shifting from a 2 wt% Re‐containing catalyst to a 0.5 wt% one, confirming the enhancement of stability. The regeneration of a low‐loading ReOx‐Pd/CeO2 (0.5 wt% Re) can be completely achieved via heat‐treatment under air in milder conditions at a temperature as low as 353 K. Based on Raman spectroscopy, no sign of polymeric ReOx could be detected on the surface of a spent ReOx‐Pd/CeO2 (0.5 wt% Re) after a simple oven drying under air, confirming the complete redispersion of the inactive species, which was previously traced as the main cause of catalyst deactivation in the catalyst with a higher metal loading.
