Monometallic Cu and bimetallic Pd–Cu catalysts promoted by ZrO2 were prepared using impregnation method. The physicochemical properties of catalytic systems were investigated using BET, scanning electron microscopy–energy dispersive spectrometry, temperature programmed reduction-H2, X-ray diffraction, Fourier transform infrared techniques. Catalytic activity was studied in fixed bed reactor under...
Bimetallic Au3M (M = Ni, Co, Fe) nanoparticles (NPs) were synthesized by reducing a mixture of Au3+ and metal cations (Ni2+, Co2+, Fe3+) by butyllithium in the presence of oleylamine. Au3M NPs were then deposited onto a commercial SiO2 support. The Au3M/SiO2 samples were not particularly active in the catalytic reduction of p-nitrophenol unless they were converted into Au–MOx/SiO2 after appropriate...
