Atom efficient PtCu bimetallic catalysts and ultra dilute alloys for the selective hydrogenation of furfural
نویسندگان
چکیده
A range of Pt:Cu bimetallic nanoparticles were investigated for the liquid-phase selective hydrogenation furfural, an important platform biomass feedstock. Alloying two metals had a profound effect on overall catalytic activity, providing superior rates reaction and achieving needed high selectivity towards furfuryl alcohol. Furthermore, we activity Ultra Dilute Alloy (UDA) formed via galvanic replacement Cu atoms by Pt dispersed host (atomic ratio 1:20). This UDA, after overcoming induction period, exhibits exceptionally initial under modest hydrogen pressures 10 20 bar, rivalling turnover monometallic (containing 12 times more Pt), outdoing pure or other compositions nanoparticle alloy catalysts. These atom efficient catalysts are ideal candidates valorization furfural due to their vastly greater economic viability.

Finding Furfural Hydrogenation Catalysts via Predictive Modelling
We combine multicomponent reactions, catalytic performance studies and predictive modelling to find transfer hydrogenation catalysts. An initial set of 18 ruthenium-carbene complexes were synthesized and screened in the transfer hydrogenation of furfural to furfurol with isopropyl alcohol complexes gave varied yields, from 62% up to >99.9%, with no obvious structure/activity correlations. Contr...

In this work, the desorption of furfural, which is a competitive intermediate during the production of biofuel and valuable aromatic compounds, was studied using pure alumina, as well as alumina impregnated with iron and platinum oxides both individually and in combination, using thermogravimetric analysis (TGA). The bimetallic sample exhibited the lowest desorption percentage for furfural. Hig...

Selective hydrogenation of 1,3-butadiene on platinum–copper alloys at the single-atom limit
Platinum is ubiquitous in the production sectors of chemicals and fuels; however, its scarcity in nature and high price will limit future proliferation of platinum-catalysed reactions. One promising approach to conserve platinum involves understanding the smallest number of platinum atoms needed to catalyse a reaction, then designing catalysts with the minimal platinum ensembles. Here we design...

The use of biomass-derived compounds as substitutes of pet roleum has received much a t tent ion1)~4). Because of the complex nature of biomass, the conversions of biomass to chemicals usually start with the production of small molecules called platform chemicals by thermal, chemical or biological processing5). Among these platform chemicals, furfural6) and 5hydroxymethylfurfural (HMF)7) are es...
