RETRACTED: Effects of N Doping on Structure and Improvement Photocatalytic Properties of Anatase TiO2 Nanoparticles

Effects of N Doping on Structure and Improvement Photocatalytic Properties of Anatase TiO2 Nanoparticles

INTRODUCTION As one of the most promising photocatalysts for the degradation of organic pollutants, TiO 2 has attracted significant attention and it has biologically and chemically inert, mechanically robust, nontoxic, cheap, environmental freindliness and therefore a perfect candidate for wide scale application with high efficiency [1-4]. However, TiO 2 nanoparticles due to the band-gap of 3.0...

Influences of Doping on Photocatalytic Properties of TiO2 Photocatalyst

As a kind of highly effective, low‐cost, and stable photocatalysts, TiO2 has received substantial public and scientific attention. However, it can only be activated under ultraviolet light irradiation due to its wide bandgap, high recombination, and weak separation efficiency of carriers. Doping is an effective method to extend the light absorption to the visible light region. In this chapter, ...

control 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...

The Influence of Ag Doping on Structural, Optical Properties and Photocatalytic Activity of TiO2/SiO2 Nanocomposite

In the present study, TiO 2 /SiO 2 and TiO 2 /SiO 2 /Ag nanocomposite powders were synthesized by sol-gel technique. Moreover, for investigation of the Ag doping effect different concentrations of dopant were added. Structures were characterized by IR spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX), and X-Ray Diffraction (XRD) methods. Fur...

Structural and electronic properties of N-doped TiO2 anatase nanoparticles and their effects on the adsorption of Hydrazine (N2H4) molecule: A first-principles study

We have performed a density functional theory investigation on the structural and electronic properties of pristine and Nitrogen-doped TiO2 anatase nanoparticles as the adsorbents for removal and degradation of hydrazine molecules in the environment. We have presented the most stable adsorption configurations and examined the interaction of hydrazine molecule with these doped and undoped nanopa...
