“…Among the catalysts tested, 0.3Re-0.3Ru/MC showed the highest TOF (61.2 h −1 ) and TOF BDO (8.51 h −1 ). In particular, the catalytic performance of 0.3Re-0.3Ru/MC was comparable to that of reported Re-based bimetallic catalysts [14][15][16][17]. This implies that 0.3Re-0.3Ru/MC served as a promising catalyst for the selective formation of BDO from succinic acid.…”

“…Among these catalysts, rhenium has been considered as the most efficient monometallic catalyst for the selective formation of BDO. However, several studies have shown that rhenium alone was not sufficient to obtain high yield for BDO [5,[14][15][16][17].…”

“…In an attempt to improve BDO production by hydrogenation of succinic acid, Re-based bimetallic catalysts, including Re-Pt/C [14], Re-Pd/C [14,15], Re-Pd/TiO 2 [16], and Re-Ru/C [15,17], have been investigated. Nonetheless, the researches have rarely elucidated the effect of interaction between rhenium and other metal on the selective formation of BDO from succinic acid.…”

“…The catalytic performance, depending on the sizes of noble metals, can also be elucidated in Table 1 including comparative literatures [22,24,29]. The selectivity to GBL is reduced from 99% to 85% (entries 2-7) with an average particle size raised from 0.8 nm to 2.5 nm, owing to the increased multiple active species.…”

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.

“…Catalyst preparation methods have been devised that promote Pd-Re interactions and minimize Re-support interactions. These include catalytic reduction, wherein chemisorbed H on the surface of Pd particles reduces perrhenate ions adsorbed from solution [25][26][27], and the directed deposition technique, wherein a Pd precursor is deposited on reduced Re particles [28][29][30]. Both of these methods, however, require preparation and handling of air-sensitive samples under an inert atmosphere, and the loading of Re (or Pd) is restricted based on the metal surface area of the parent catalyst.…”

a b s t r a c tThe double complex salt [Pd(NH 3 ) 4 ](ReO 4 ) 2 was employed as precursor of supported bimetallic catalysts for selective hydrogenation of furfural. Direct reduction of [Pd(NH 3 ) 4 ](ReO 4 ) 2 on c-Al 2 O 3 in flowing H 2 at 400°C yields bimetallic nanoparticles 1-2 nm in size that exhibit significant interaction between the metals, as evidenced by temperature-programmed hydride decomposition (complete suppression of b-PdH x formation), extended X-ray absorption fine structure spectroscopy at the Pd K and Re L III edges (PdARe distance = 2.72 Å), and scanning transmission electron microscopy with energy dispersive X-ray analysis. In contrast, calcination of [Pd(NH 3 ) 4 ](ReO 4 ) 2 on c-Al 2 O 3 at 350°C in air and subsequent reduction in H 2 at 400°C results in metal segregation and formation of large (>50 nm) supported Pd particles; Re species cover the Pd particles and c-Al 2 O 3 support. A PdRe 1:2 catalyst prepared by sequential impregnation and calcination using HReO 4 and [Pd(NH 3 ) 4 ](NO 3 ) 2 has a similar morphology.The catalyst derived by direct reduction of [Pd(NH 3 ) 4 ](ReO 4 ) 2 on c-Al 2 O 3 exhibits remarkably high activity for selective hydrogenation of furfural to furfuryl alcohol (FAL) at 150°C and 1 atm. Suppression of H 2 chemisorption via elimination of Pd threefold sites, as evidenced by CO diffuse-reflectance infrared Fourier transform spectroscopy, correlates with increased FAL selectivity.
