Ammonia treated Mo/AC catalysts for CO hydrogenation with improved oxygenates selectivity

Hydrogenation of Biomass Derived Oxygenates

Condensation/Hydrogenation of Biomass- Derived Oxygenates in Water/Oil Emulsions Stabilized by Nanohybrid Catalysts

The synthesis of fuel-range molecules by condensation of biomass-derived furfural and acetone has been studied in a biphasic emulsion system. Nanohybrids composed of basic oxide nanoparticles fused to carbon nanotubes have been used to simultaneously stabilize water/oil emulsions and catalyze the condensation reaction. Under the same conditions, higher conversions and higher fractions of fuel-r...

CO Hydrogenation over Alumina-Supported Sulfide Cluster Catalysts

Bimetallic Mo-Fe and Mo-Co sulfide clusters were anchored on AI,O, and used for CO hydrogenation. In addition to methane, significant amounts of dimethyl ether were produced. The reaction orders obtained from power rate laws for methanation indicated that the surfaces of the catalytic ensembles were not completely saturated by CO, in contrast to the observations for most conventional CO hydroge...

Surface Interactions of Biomass Derived Oxygenates with Heterogeneous Catalysts

Size-controlled model Co nanoparticle catalysts for CO₂ hydrogenation: synthesis, characterization, and catalytic reactions.

Model cobalt catalysts for CO(2) hydrogenation were prepared using colloidal chemistry. The turnover frequency at 6 bar and at 200-300 °C increased with cobalt nanoparticle size from 3 to 10 nm. It was demonstrated that near monodisperse nanoparticles in the size range of 3-10 nm could be generated without using trioctylphosphine oxide, a capping ligand that we demonstrate results in phosphorus...
