“…Therefore, the supported copper also had little promotive or inhibitive effect on the glycerol dehydration to 3-hydroxypropanal over supported STA. Supported STA is unable to catalyze 3-hydroxypropanal hydrogenation, while copper metal is active for this reaction [21,22]. From the above discussion, it is suggested that 1,3-PD is mainly produced through the designed pathway (step 1 and step 2 in Scheme 2).…”

Using a SiO 2 supported copper and H 4 SiW 12 O 40 catalyst, it is demonstrated that glycerol can be directly converted to 1,3-Propanediol (1,3-PD) through vapor-phase process under pressure below 0.54 MPa, without employing environmentally harmful organic solvent. The formation of 1,3-PD is proved to proceed through the designed reaction pathway: (step 1) dehydration of glycerol to 3-hydroxypropanal on acid site of supported H 4 SiW 12 O 40 (step 2) hydrogenation of 3-hydroxypropanal on supported copper metal. The effect of temperature, weight hourly space velocity, pressure, and initial water content was investigated to obtain the optimum conditions. The glycerol conversion and products distribution greatly depended on these factors. Both the 1,3-PD and 1,2-Propanediol selectivity improved with increasing hydrogen pressure. At 210°C, 0.54 MPa and 83.4% conversion, the selectivity of 1,3-PD was up to 32.1%, together with a 22.2% selectivity of 1,2-Propanediol. The cyclic acetal, an important kind of byproducts, was identified by Gas Chromatogram-Mass Spectrometer (GC-MS).

“…Recently, the authors' group also screened more than twenty kinds of acid catalyst (including SiO 2 supported [21,22]. More important, copper has poor activity towards C-C cleavage, so few degradation products are formed over Cu-based catalysts [12,21].…”

“…36 The first shoulder peak at 270 ℃ was assigned to the reduction of surface CuO and the second shoulder peak was perhaps the contribution of bulk-like Cu 2＋ species. 35,36 However, the first shoulder peak for Cu 11.2 Ni y -MgAlO samples disappeared with the species could convert the surface CuO species into increasing nickel amount, probably because that Ni (1) 0, (2) 2.4%, (3) 4.7%, (4) 7.1% and (5) (Figure 2). Thus it was concluded that the octahedral Cu species in CuAl 2 O 4 -like spinel phases were probably the best active catalytic centers.…”

The nickel-promoted Cu-containing catalysts (Cu x Ni y -MgAlO) for furfural (FFR) hydrogenation were prepared from the hydrotalcite-like precursors, and characterized by X-ray powder diffraction, inductively-coupled plasma atomic emission spectroscopy, N 2 adsorption-desorption, UV-Vis diffuse reflectance spectra and temperatureprogrammed reduction with H 2 in the present work. The obtained catalysts were observed to exhibit a better catalytic property than the corresponding Cu-MgAlO or Ni-MgAlO samples in FFR hydrogenation, and the CuNi-MgAlO catalyst with the actual Cu and Ni loadings of 12.5 wt% and 4.5 wt%, respectively, could give the highest FFR conversion (93.2%) and furfuryl alcohol selectivity (89.2%). At the same time, Cu 0 species from the reduction of Cu 2＋ ions in spinel phases were deduced to be more active for FFR hydrogenation.

“…Hydrogenation of cinnamaldehyde usually uses selective catalysts (Pt, Cu, Rh etc) for the synthesis of derivatives such as hydrocinnamaldehyde and cinnamyl alcohol as a sole product [35][36][37] . Other process hydroformylation of styrene in presence of rhodium complexes as catalyst form is phenyl-propanal 37 .…”
