v2o5/sio2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethylorthosilicate in refluxing meoh, followed by calcination at 700 °c for 2 hours. the resultant nanoparticles was characterized by means of scanning electron microscopy (sem), transmission electron microscopy (tem), x-ray diffraction (xrd), tga and ftir techniques. rapid and efficient ar...
Abstract The Pt(II) acetylacetonate complex [(L)Pt(Acac)] based on aminophenyl-substituted 2-(2-thienyl)pyridine (L) was synthesized, its photophysical properties were studied and compared with these for a similar containing no amino group in the ligand. structure of confirmed by X-ray diffraction (CIF file CCDC no. 2144689), 1 H 13 C NMR spectroscopy, ESI mass spectrometry, elemental analysis.
A library of platinum (II) complexes general formula (O,O′-β-diketonate)PtLX (L = dimethylsulfoxide, pyridine, triphenylphosphine; X chloride, γ-acetylacetonate) has been prepared, using synthetic methodologies available in the literature. The supplemented with a novel complex bearing triazenido N-oxide ligand. have characterized and tested as precatalysts for photoactivated curing silicone res...
Chemically disordered B3–7-nm-diameter FePt nanoparticles are synthesized using the airless operation technique based on decomposition of iron pentacarbonyl and reduction of platinum acetylacetonate. The particle solution is then washed and subsequently deposited onto a thermally oxidized Si substrate. Nanoparticle assemblies are formed after solvent evaporation. The samples are heat-treated us...
Introduction Highly dispersed supported gold catalysts have attracted wide interest because of their high activities and selectivities for reactions including low-temperature oxidation of CO, even in the presence of H2. Notwithstanding extensive research on supported gold catalysts, fundamental questions remain, such as what are the catalytically active sites and reaction mechanisms. By using A...
Catalytic performances of promoted CoMoS catalysts were greatly improved via a synthesis strategy based on the structuration active phase using self-assembled PANI (Polyaniline) nanowires followed by an addition step cobalt acetylacetonate oxidic or sulfided Mo-based hybrids. Taking into account different promotion levels, slabs lengths determined XPS and TEM, highest rate constants normalized ...
various radiometal complexes have been developed for tumor imaging, especially ga-68 tracer. in the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67ga] acetylacetonate bis(thiosemicarbazone) complex ([67ga] aats) was prepared starting [67ga]gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (aats) in 30 min at 90°c. ...
