Selective liquid-phase hydrogenation of furfural to furfuryl alcohol over Cu-based catalysts
(Elsevier, 2013-02)
In this work, the liquid-phase furfural hydrogenation over different Cu-based catalysts was studied. The catalysts were prepared by incipient wetness impregnation (Cu/SiO2-I), precipitation?deposition(Cu/SiO2-PD) and ...

Crystal structure, Raman scattering and magnetic properties of CuCr2-xZrxSe4 and CuCr2-xSnxSe4 selenospinels
(Elsevier, 2018)
Selenospinels, CuCr2-xMxSe4 (M = Zr and Sn), were synthesized via conventional solid-state reactions. The crystal structure of CuCr1.5Sn0.5Se4, CuCr1.7Sn0.3Se4, CuCr1.5Zr0.5Se4, and CuCr1.8Zr0.2Se4 were determined using ...
Cu/Al and Cu/Cr based layered double hydroxide nanoparticles as adsorption materials for water treatment
(2018)
Cu/Al and Cu/Cr layered double hydroxides (LDH) were synthesized using a simple co-precipitation method at room temperature. These particles were further modified by Co+2 incorporation, and calcined at 500 degrees C for ...
Synthesis and magnetic properties of chromium‑based cu(cr‑ti)s thiospinels and their deficient structures cu‑cr ti s obtained by copper extraction
(2014)
The crystalline structure of spinels is extremely flexible due to the presence of several sublattices in which the cations can be distributed and localized in
different crystallographic sites depending on their sizes, ...
