Solar Photocatalytic Degradation of Diclofenac by N-Doped TiO2 Nanoparticles Synthesized by Ultrasound
Anatase N-doped TiO2 nanoparticles were synthesized using ultrasound at low frequency and room temperature. The samples characterized by techniques including XRD, TEM, HRTEM, FT-IR, XPS, and UV–Vis spectroscopy. XPS indicated the existence of nitrogen as an anion dopant within the TiO2 lattice. The solar photocatalytic activity of N-doped TiO2 studied for th...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

متن کاملSynthesis and Characterization of N-Doped Porous TiO2 Hollow Spheres and Their Photocatalytic and Optical Properties
Three kinds of N-doped mesoporous TiO₂ hollow spheres with different N-doping contents, surface area, and pore size distributions were prepared based on a sol-gel synthesis and combined with a calcination process. Melamine formaldehyde (MF) microspheres have been used as sacrificial template and cetyltrimethyl ammonium bromide (CTAB) or polyvinylpyrrolidone (PVP) was selected as pore-directing ...
متن کاملSynthesis and Characterization of Doped TiO2 Nanoparticles by the Sol-Gel Method and Investigation of Photocatalytic Activity
Cu2+,Ce3+-doped nanostructure TiO2 -coated Nd3+ (TiO2 /Nd3+) were prepared by sol-gel method. TiO2 were synthesized by the sol-gel method using tetra n-butyl orthotitanat (TBT) as a precursor. The prepared nanoparticles characterized by FT-IR, XRD, SEM- EDS and TEM. The XRD showed that the major phase of nanocomposite is anatase. The morphology of the TiO2/Nd3+/Cu2+and TiO2 /Nd3+/Ce3+ microsphe...
