This report portrays the analysis of Cu doping concentration (%) on PbS thin films prepared by feasible nebulizer spray technique. The percentage was increased from 0% to 8% in steps 2%. X-ray diffraction study evinces nature as polycrystalline with simple cubic crystal structure. calculated crystallite size varied 55 41 nm increasing concentration. SEM/AFM studies proclaim that shaped grains have covered entire film surface. shape amended respect increase An elevation band gap 1.61 eV 2.10...

Rhodium nanoparticles (≈3-5 nm) were incorporated into the 3D mesoporous TUD-1 material by using sol-gel technique. The prepared catalyst shows high activity in liquid phase conversion of cyclohexene to cyclohexane at room temperature (298 K), 1 atm H2 pressure, and under solvent-free conditions. exhibited stability, reusability negligible leaching.

Nickel oxide powder was prepared by simple calcination of nickel nitrate hexahydrate at 500 °C for 5 h and used as a catalyst the oxidation cyclohexane to produce cyclohexanone cyclohexanol—KA oil. Molecular oxygen (O2), hydrogen peroxide (H2O2), t-butyl (TBHP) meta-chloroperoxybenzoic acid (m-CPBA) were evaluated oxidizing agents under different conditions. m-CPBA exhibited higher catalytic activity compared other oxidants. Using 1.5 equivalent an donor agent 24 70 °C, in acetonitrile...

Rhodium (Rh) nanoparticles were embedded in the mesopores of TUD-1 siliceous material and denoted as Rh-TUD-1. Five samples Rh-TUD-1 prepared with different loadings Rh that ranged from 0.1 to 2 wt% using sol-gel technique. The characterized by means several chemical physical techniques. obtained characterization results show formation highly distributed Rh0 an average size ranging 3 5 nm throughout three-dimensional silica matrix TUD-1. catalytic activity catalysts was evaluated...

Four different metal nanoparticles (metal = Ag, Ru, Pt, or Rh) were impregnated on the acidic cesium salt of tungstophosphoric acid Cs2.5H0.5PW12O40 (CsPW) with a loading amount 2 wt%. The prepared catalysts characterized by using X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FTIR), N2 sorption measurements, scanning electron microscopy (SEM), and energy-dispersive (EDX). Results confirmed formation highly distributed metallic nanoparticle centres over CsPW. catalytic...

In this study, a novel and simple synthetic sol-gel procedure was established to directly prepare spherical lead titanate powders without prior synthesis/usage of templates such as TiO2 particles. Isotropic submicron particles with mean diameter 1–4 μm were prepared in way. This process takes advantage acetone stabilizing ligand autogenous pressure generated the autoclave during reaction. The influence various experimental factors (nature ligand, thermal treatment mode, post-calcining...
