Titanium (IV) isopropoxide (TTIP) was used for preparing TiO2 nanoparticles by the precipitation technique. The precipitation was carried out following two experimental routes. In the first route titanium (IV) isopropoxide was mixing in ethanol, the solution obtained was heated at 60°C, then; glacial acetic acid and sulfuric acid were slowly added under constant magnetic stirring. In the second route...
Alumina mixed tin oxide (SnO2: Al2O3) powders were obtained by employing chemical and physical synthesis methods. The powders were prepared from tin chloride as Sn source, urea (R1) and ammonia (R2) as precipitant agents. The resultant SnO2 powders are milled in a planetary ball mill. Finally, Al2O3 was added to the milled SnO2 powders manually in different ratios, and then pressed to manufacture...
Platinum doped tin oxide (SnO2: Pt) powders were obtained by employing novel methods, which are a mixture of chemical and physical synthesis methods. The powders were prepared from tin chloride and urea as precipitant agent. The resultant SnO2 powders are milled in a planetary ball mill. Finally, a noble metal, platinum (Pt), was added to the milled SnO2 powders via bulk and surface doping methods,...
Nanoparticles of Titanium dioxide (TiO2) in anatase phase have been synthesized through a homogeneous precipitation method using titanium butoxide (Ti(OBu)4 as precursor of Ti. The synthesis was performed by mixing (Ti(OBu)4 in ethanol at 55°C. Then, glacial acetic acid and sulfuric acid were slowly added under constant magnetic stirring until obtaining a white precipitate. Afterwards, this precipitate...
Tin oxide (SnO2) powders were obtained by the homogeneous precipitation method by using urea as precipitation agent. The SnO2 powders were later ball milled for using a homemade stainless steel die and pressed with a pressing machine to manufacture thin pellets. After several experimental trials, stable SnO2 pellets were formed by manual pressing. Copper (Cu) modified SnO2 pellets (Cu-SnO2) were prepared...
Tin oxide (SnO2) powders were obtained by the homogeneous precipitation method from a 0.4 M starting solution prepared from tin chloride as tin precursor and urea as precipitation agent. The SnO2 powders were ball milled at 4, 6 and 8 h and two different speeds, 300 and 400 rpm. Structural analysis was performed by X-Ray diffraction (XRD) to confirm the SnO2 rutile phase. In this work the crystallite...
