Several lanthanum oxide-modified Cu/SiO2 (La-Cu/SiO2) catalysts synthesized by urea-assisted gelation and postimpregnation were used for the vapor-phase chemoselective hydrogenation of dimethyl oxalate (DMO) into ethylene glycol (EG). The 1.0La-Cu/SiO2-u catalyst with 1.0 wt % La loading was found to have highest activity, whereas higher at 3.0 adversely affected deterioration catalytic activity. H2-TPR results revealed that strong interactions between promoters Cu species substantially...
Abstract Metal-support interaction is one of the most important parameters in controlling catalysis supported metal catalysts. Silica, a widely used oxide support, has been rarely reported as an effective support to create active metal-support interfaces for promoting catalysis. In this work, by coating Cu microparticles with mesoporous SiO 2 , we discover that Cu/SiO interface creates exceptional effect promote catalytic hydrogenation esters. Both computational and experimental studies...
Bulk chemicals such as ethylene glycol (EG) can be industrially synthesized from either or syngas, but the latter undergoes a bottleneck reaction and requires high hydrogen pressures. We show that fullerene (exemplified by C60) act an electron buffer for copper-silica catalyst (Cu/SiO2). Hydrogenation of dimethyl oxalate over C60-Cu/SiO2 at ambient pressure temperatures 180° to 190°C had EG yield up 98 ± 1%. In kilogram-scale reaction, no deactivation was seen after 1000 hours. This mild...
Abstract Selective hydrogenation and hydrogenolysis of 5‐hydroxymethylfurfural were performed with carbon nanotube‐supported bimetallic NiFe (NiFe/CNT) catalysts. The combination Ni Fe in an appropriate atomic ratio Ni/Fe (2.0) significantly increased the selectivity to 2,5‐furandimethanol or 2,5‐dimethylfuran depending on reaction temperature. selectivities as high 96.1 % at 383 K 91.3 473 K, respectively. characterization results confirmed that particles sizes less than 7 nm formed...
An ordered mesoporous carbon (CMK-3)-supported gold catalyst was prepared and used in the aerobic oxidation of glucose to gluconic acid under base-free conditions with molecular oxygen. XRD TEM results revealed that nanoparticles were uniformly dispersed on surface channels CMK-3. Catalytic tests showed conversion remarkably increased decreased selectivity when oxygen pressure reaction temperature increased. Glucose reached over 92% 85% 383 K temperature, 0.3 MPa pressure, 2 h time. Hydrogen...
Replacement of Hg with non-toxic Au based catalysts for industrial hydrochlorination acetylene to vinyl chloride is urgently required. However suffer from progressive deactivation caused by auto-reduction Au(I) and Au(III) active sites irreversible aggregation Au(0) inactive sites. Here we show synchrotron X-ray absorption, STEM imaging DFT modelling that the availability ceria(110) surface renders Au(0)/Au(I) as pairs. Thus, directly involved in catalysis. Owing strong mediating properties...

The performance of an SBA-15-supported Cu catalyst for hydrogenation dimethyl oxalate to ethylene glycol is markedly promoted with Au. A key genesis the high activity ascribed formation Cu–Au alloy nanoparticles which stabilize active species and retard their agglomeration during process.
Carbon nanotube-supported RuFe bimetallic catalysts (RuFe/CNT) were prepared through a coimpregnation method for the selective hydrogenolysis of 20 wt % glycerol aqueous solution to produce glycols (1,2-propanediol and ethylene glycol).
