Highly selective and stable ZnO-supported bimetallic RuSn catalyst for the hydrogenation of octanoic acid to octanol

Investigation of Parameters Influencing the Activity and Selectivity of Ru-Sn Catalyst for Chemoselective Hydrogenation of Benzoic Acid to Benzyl Alcohol

“…According to DFT calculations selective hydrogenation of benzoic acid to benzyl alcohol over Pt/SnO2 catalyst occurred due to selective absorption of carboxylic group instead of aromatic ring of benzoic acid [5]. For hydrogenation of octanoic acid Ru-Sn supported on ZnO catalyst gives 99.4% conversion and 93.0% selective to octanol [6,7]. To date, no comprehensive study has been conducted on the influence of the Sn/Ru ratio in the Ru-Sn/Al2O3 catalyst on the hydrogenation of aromatic carboxylic acids, which could elucidate the role of Sn in inhibiting hydrogenolysis.…”

Bimetallic Ru-Sn as Effective Catalysts for the Selective Hydrogenation of Biogenic Platform Chemicals at Room Temperature

“…Most recently, Ru-Sn/ZnO catalyst was employed for hydrogenation of octanoic acid to octanol in a fixed-bed continuous reactor system at elevated temperatures (300 °C) and 30 bar H2. The presence of Ru3Sn7 al-loy phase was the active site for the significant improvement of the hydrogenation activity and selectivity to octanol as well as the stability in long-term reactions [35].…”

Selective hydroconversion of coconut oil-derived lauric acid to alcohol and aliphatic alkane over MoOx-modified Ru catalysts under mild conditions

“…They claimed that Ru 3 Sn 7 and SnO x were active species in the bimetallic Ru-Sn catalyst as indicated by the conversion and product selectivity, and computational modelling calculation. 37,38 In the case of direct modication of PGM with metal oxides, oxophilic metal oxides (e.g., ReO x , MoO x , and WO x )-modied PGM-based catalysts showed excellent performance for the catalytic HDO of biomass-derived oxygenates into chemicals and fuels. [39][40][41][42][43][44][45] The presence of oxophilic metal oxides played the bifunctional catalytic roles, whereas the metal sites can catalyse the hydrogen uptake, dissociation, and spill-over onto the metal-oxide in vicinity.…”
