Highly dispersed copper nanoparticles supported on silica were successfully prepared by a simple and convenient precipitation−gel technique, their physicochemical properties activity compared to those of catalyst the conventional impregnation method. As consequence preparation method, texture (BET), dispersion (dissociative N2O adsorption), morphology (TEM), reduction behavior (TPR, XRD), state species (XPS), catalytic performance (glycerol hydrogenolysis) differ between samples. Both...
In this work, we report a novel and facile procedure for one-pot preparation of palladium nanoparticle catalysts supported on porous N-doped carbon (Pd@CNT) by direct carbonization palladium-N-heterocyclic carbene coordination polymer (P-Pd-NHC). This method could be conveniently extended to the synthesis Ni alloy (PdxNiy) (Ni@CN800, PdxNiy@CN800). The treatment temperature played an important role growth properties resultant M@CNT, wherein M@CN800 carbonized at 800 °C showed...
Copper–silica nanocomposite catalysts have been found to be highly efficient and stable in the heterogeneous hydrogenation of CO 2 -derived cyclic carbonates give methanol diols under relatively mild conditions.
Hydrogenolysis of biomass-derived furfuryl alcohol to 1,2-pentanediol and 1,5-pentanediol with high yield (~80%) could be achieved over a simple but efficient non-precious Cu–Mg<sub>3</sub>AlO<sub>4.5</sub> bifunctional catalyst at mild conditions.
Biomass has attracted great attention as a carbon source for the production of valuable chemicals and fuels. Selective ring-opening hydrogenation cyclic oxygenates derived from biomass offers promising approaches catalytic synthesis value-added oxygen-containing compounds compared to corresponding fossil-based protocols. Different sites are required perform distinct types elementary reaction steps (e.g., adsorption activation groups, association hydrogen molecule), thus synergistic effect...
Titania-supported monometallic and bimetallic Cu–Co catalysts were prepared using (co)impregnation studied for the hydrogenation of γ-butyrolactone (GBL) to 1,4-butanediol (BDO) at temperatures from 100 180 °C a hydrogen pressure 3.4 MPa. The highest catalytic activity occurred Cu:Co atomic ratio 1:9 (Cu0.1Co0.9/TiO2), 95% yield BDO was obtained. Characterization results showed mainly small nanoparticles (average size 2.6 nm) pure Cu/TiO2, large particles (∼19.8 Co/TiO2, bimodal particle...

Heterogeneous catalytic reductive amination of biomass-based carbonyl compounds is a highly attractive strategy to realize green and sustainable amine synthesis under mild conditions. Herein, N1,N1-diethyl-1,4-pentanediamine, key side chain chloroquine pharmaceuticals, was selectively synthesized through the 5-diethylamino-2-pentanone on active NixAl nanocatalysts with different Ni/Al molar ratios prepared by simple co-precipitation method. The Ni1Al catalyst presented highest target diamine...
Abstract The selective hydrogenolysis of biomass‐derived xylitol to ethylene glycol and propylene was performed on Cu–SiO 2 catalysts prepared by a precipitation–gel method with different Cu contents pretreatment temperatures.

Bio-based furanic oxygenates represent a well-known class of lignocellulosic biomass-derived platform molecules. In the presence H2 and different nitrogen sources, these versatile building blocks can be transformed into valuable amine compounds via reductive amination or hydrogen-borrowing mechanisms, yet they still face many challenges due to co-existence side-reactions, such as direct hydrogenation, polymerization cyclization. Hence, catalysts with specific structures functions are...
2,2,6,6-Tetramethylpiperidine-N-oxyl (TEMPO) has been widely employed as a catalyst in various homogeneous and heterogeneous catalytic systems.
