The catalytic oxidation of sulfur dioxide to sulfur trioxide over several binary (MxOy/TiO2) and ternary (V2O5/MXOY/TiO2) supported metal oxide catalysts was systematically investigated. The supported metal oxide components were essentially 100% dispersed as surface metal oxide species, as confirmed by Raman spectroscopy characterization. The sulfur dioxide oxidation turnover frequencies of the...

a simple and green synthetic strategy to prepare bao/tio2-zro2 as a solid base catalyst was reported. these materials with various amounts of bao were prepared by the adsorption method. the physical and chemical properties of bao/tio2-zro2 were investigated by x-ray diffraction, x-ray fluorescence, specific surface area and bjh pore size distribution, ft-ir spectroscopy, scanning electron micro...

Nano-TiO2 sol and finishing agent was prepared by sol-gel method, during which tetrabutyl titanate was used as precursor and ethanol was used as solvent. The agent was penetrated into polyester fabric through a padding method, the anti-ultraviolet performance of the fabric was analyzed and the external morphology was carefully studied afterward. The results showed that indicated that the Nano-T...

the present study was aimed to investigate the effects of titanium dioxide nanoparticles (nano-tio 2 ) on wheat ( triticumaestivum l.) plants cv. parsi. the experimental treatments included seven concentrations of nano- tio 2 (10, 100, 1000, 1200, 1500 and 1700 ppm nano-tio 2 and control (without any tio 2 ). the results showed that among the wheat germination indices, germination rate and weig...

How graphene oxide (GO) with its step edges and wrinkles (∼1-2 nm) acts as a catalyst in hydrothermal nucleation and growth is demonstrated. TiO2 whiskers were prepared by using GO as a support, while TiO2 nanograss was prepared without using GO.

In recent years, antibiotics (such as levofloxacin (LEV)) have been detected widely in the environment. Semiconductor photocatalysis has recognized a promising technology for removing pollutants this work, nitrogen and carbon codoped titanium dioxide nano-catalyst (NCD-TiO2) was immobilized polyvinyl alcohol (PVA) matrix to form PVA/NCD-TiO2 films through solution casting thermal treatment, whi...

In this study, photocatalytic degradation of diazinon was investigated using commercial nano-TiO2as a photocatalyst the operational parameters such as adsorption, aeration, pH and nano-TiO2 dosage were investigated. Dispersive liquid-liquid microextraction (DLLME) technique was used to extract and preconcentration of residual diazinon and by-products from the liquid samples and the analysis was...

Self-assembled supramolecular organization of nano-structured biomimetic light-harvesting modules inside solid-state nano-templates can be exploited to develop excellent light-harvesting materials for artificial photosynthetic devices. We present here a hybrid light-harvesting system mimicking the chlorosomal structures of the natural photosynthetic system using synthetic zinc chlorin units (Zn...

-The present work is focused on the heterogeneous photocatalytic degradation of Amaranth dye over immobilized nano-crystals of TiO2. Immobilization has been an acceptable approach to overcome the drawbacks encountered with powder suspensions. Immobilization is performed using polyvinyl alcohol-formaldehyde binder. This method of immobilization does not require thermal heating at high temperatur...
