“…Various mono and bimetallic catalysts have been examined in the literature for the liquid phase hydrogenation of succinic acid to GBL, BDO and THF [10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The most active catalysts for the synthesis of BDO or THF contain a first component, which is a noble metal (Pd, Ru, or Pt) and a second component which is rhenium, tin, or cobalt.…”

TiO2-supported Re-Pd catalysts were evaluated for the selective hydrogenation of succinic acid (SUC) to 1,4-butanediol (BDO) in aqueous solution at 160 °C under 150 bar of H2. Rhenium immobilized on Pd/TiO2 catalysts by ex situ preparation methods, namely successive impregnation (SI) or deposition by catalytic reduction (CR), was partially leached after handling in air and introduction into the SUC aqueous solution in the batch reactor; it was then re-deposited under H2 pressure. It was demonstrated in this study that Re can be deposited by CR on a monometallic Pd catalyst directly in situ in the autoclave under hydrogen pressure before the catalytic test. The Re loading and the activation time under reducing atmosphere in the autoclave were optimized. Finally, the best bimetallic catalysts synthesized in situ demonstrated an intermediate selectivity to BDO compared to the systems prepared ex situ from the same parent monometallic catalyst, in the following order: ex situ CR < in situ CR < ex situ SI.

“…Most of the studies firstly reported in the literature were conducted in 1,4-dioxane as solvent [18][19][20][21][22]24,26]. Water, which is the solvent of production of bio-SUC [10], has been used to a limited extent for this reaction until recently [12][13][14][15][16][17]23,25,[27][28][29][30].…”

“…In our work, the subnanometer Pd clusters are highly specific for the hydrogenation of SUC to GBL and avoid the further hydrogenation of GBL (Scheme 1). On the other hand, the reported Pd catalysts with a size of 2~10 nm can catalyze the subsequent hydrogenation of GBL into BDO and THF [21,22]. Accordingly, the selectivity is extremely sensitive to the metal nanoparticle size [43].…”

Abstract:The size of metal particles is an important factor to determine the performance of the supported metal catalysts. In this work, we report subnanometer Pd clusters supported on zirconia by the microwave-assisted hydrothermal method. The presence of subnanometer Pd clusters on the zirconia surface was confirmed by two-dimensional Gaussian-function fits of the aberration-corrected high-angle annual dark-field images. These subnanometer Pd catalysts exhibit high catalytic performance for the hydrogenation of biomass-derived succinic acid to γ-butyrolactone in water and avoid the formation of overhydrogenated products, such as 1,4-butanediol and tetrahydrofuran. The catalyst with an ultra-low Pd loading of 0.2 wt. % demonstrated high selectivity (95%) for γ-butyrolactone using water as a solvent at 473 K and 10 MPa. Moreover, it can be reused at least six times without the loss of catalytic activity, illustrating high performance of the small Pd clusters.
