tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. photo degradation of congo red (azo dye) showed that photo catalytic property of the as-prepared wo3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. photo degradation of rhodamine b (cationic triary...

tungsten trioxide nanoparticles with monoclinic structure and average particle size about 80 nm were prepared by the spray pyrolysis method. wo3 nanorods with hexagonal structure and average dimension about 15 × 100 nm were synthesized in gram quantities by modified hydrothermal method at lower temperature and shorter reaction time in comparison to the previous research. photo degradation of co...

Thin films of indium doped zinc sulfide (ZnS) for different indium (In) concentrations (x=0.0 - 0.8) were deposited onto glass substrate by spray pyrolysis method at 523K temperature. Aqueous solution of zinc acetate, indium chloride and thiorea were used to deposit the In-Zn-S film. The deposited thin films were characterized by Energy dispersive X-ray (EDX), Scanning electron microscopy (SEM)...

Abstract Spray pyrolysis is a method for preparing nanocomposite materials in the gas phase. Due to ease with which temperature furnace can be controlled, this produce more uniform nanoparticle sizes. This used synthesize ZnO nanoparticles. Additionally, due photocatalytic properties of synthesized particles, they are decompose synthetic dye waste. electron-hole recombination, ZnO’s limited. A ...

The direct synthesis of Dimethyl carbonate (DMC) from methanol and CO2 is a green process which allows valorization. Among efficient catalysts, ceria, zirconia cerium-zirconium mixed oxides are often reported as the most active catalysts. In recent report, we discovered that prepared by Flame Spray Pyrolysis (FSP) show greater catalytic activities than those precipitation, although both exhibit...

Transition metal fluorides (such as FeF3 or CoF2) promise significantly higher theoretical capacities (>571 mAh g(-1)) than the cathode materials currently used in Li-ion batteries. However, their practical application faces major challenges that include poor electrochemical reversibility induced by the repeated bond-breaking and formation and the accompanied volume changes and the difficulty o...
