Effect of the nature of carbon support on the formation of active sites in Pd/C and Ru/C catalysts for hydrogenation of furfural

Structure‐Reactivity Relations in Ruthenium Catalysed Furfural Hydrogenation

“…Mironenko et al. likewise observed poor activity for aqueous phase furfural hydrogenation over Ru NPs on carbon nanotubes and carbon black, albeit under more mild reaction conditions (50 °C, 5 bar H 2 ) and attributed to strong water adsorption . Furfuryl alcohol selectivity is broadly independent of support, and exceeds 85 %, for aqueous phase hydrogenation under mild conditions: 2 wt% Ru NPs over SiO 2 , ZrO 2 , and Al 2 O 3 (under mild conditions of 30 °C and 5 bar H 2 ); 5 wt% Ru NPs over MgO, hydrotalcite, activated carbon, and CaO (at 110 °C and 4 bar H 2 ); 3 wt% Ru NPs dispersed within Zr‐ and Al‐containing MOFs (20 °C and 5 bar H 2 ); 4 wt% Ru over graphene oxides .…”

Catalysts based on large size-controlled Pd nanoparticles for aqueous-phase hydrodechlorination

“…Particularly, carbon blacks (CB) have been widely used as catalysts supports in several reactions such as hydrogenation [44,45], oxygen reduction [46] and electro-oxidation [47], being their good electrical conductivity one of the most remarkable properties that seems to play a significant role in catalysis [44,47,48].…”

Performance of Cu/TiO2‐SiO2 catalysts in hydrogenation of furfural to furfuryl alcohol

“…The C═O in FFR molecules and the C═C on the furan rings determine that the hydrogenation mainly involves the C═O in carbonyl and the C═C in furan rings, which will form FFA or tetrahydrofurfural derivatives . The route of FFR catalytic hydrogenation appears in Figure .…”

“…FFA is mainly produced by the gas‐phase or liquid‐phase hydrogenation of FFR. Metals such as Cu, Co, Ni, Ru, Rh, Pd, and Pt are normally chosen as active components for this hydrogenation. Among them, the copper‐chromite (Cu‐Cr) catalyst has been the most commercially successful for decades.…”
