THE EFFECT OF CALCINATION TEMPERATURE TO COMPOSITECHARACTERISTICS TiO2SiO2 NANOPARTICLE. Self-cleaning material is a that utilizes the photocatalytic property to degrade organic and inorganic compounds with help of UV light. One materials have good TiO2, causes TiO2 be amphiphilic: becomes hydrophilic when there light hydrophobic no The can improved addition buffer such as SiO2. nanoparticle wa...

Heterojunction photocatalytic materials show excellent performance in degrading toxic pollutants. This study investigates the influence of calcination temperature on performances floral Bi2O3/TiO2 composite photocatalyst crystal, which was prepared with glycerol, bismuth nitrate, and titanium tetrachloride as major raw via solvothermal method. XRD, SEM/TEM, BET, Uv-vis, XPS were employed to ana...

Co3O4 catalysts were prepared via carbonate precipitation and subsequent calcination under specific conditions. The different characterized as received using several techniques tested in the total oxidation of toluene or propane. Calcination at low temperature dynamic conditions resulted with small crystallite sizes large surface areas. performances appeared to be closely related low-temperatur...

In this research, Effect of thermal treatment on beneficiation of low-grade laterite nickel by calcination-magnetic separation method was studied. In order to determine the components and elements of the sample, to recognize the main and minor minerals and their bond, and phase transformation caused by thermal treatment, Chemical analysis (XRF and ICP), microscopic studies and XRD analysis ...

−A study of the phase transformations generated by chlorine during the calcination of clays and kaolins is presented. The original samples and residues of the thermal treatment carried out in air and chlorine atmospheres are analyzed at different calcination times and temperatures. Sample characterization was performed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Xray micr...

We report herein a straightforward and label-free approach to prepare luminescent mesoporous silica nanoparticles. We found that calcination at 400 °C can grant mesoporous organosilica nanoparticles with strong fluorescence of great photo- and chemical stability. The luminescence is found to originate from the carbon dots generated from the calcination, rather than the defects in the silica mat...
