BTX compounds (Benzene, toluene and xylenes) are the main pollutants in air and fuels. Recent environmental legislations are limited the amount of these materials specially the amount of benzene in gasoline due to its carcinogen effects on health. In this research, the BTX hydrogenation was carried out using nanoparticles of Co supported on MWCNTs (multiwall carbon nanotubes) and AC (activated ...

Bimetallic Cu-Ni/TiO2 photocatalysts were synthesized using wet impregnation (WI) method with TiO2 (Degussa-P25) as support and calcined at different temperatures (180, 200, and 300°C) for the photodegradation of DIPA under visible light. The photocatalysts were characterized using TGA, FESEM, UV-Vis diffuse reflectance spectroscopy, fourier transform infrared spectroscopy (FTIR) and temperatur...

Mesoporous silica materials (MSM) with ordered and controllable porous structure, high surface area, pore volume and thermal stability are very suitable catalyst supports, because they provide high dispersion of metal nanoparticles and facilitate the access of the substrates to the active sites. Since the conventional wet-impregnation and deposition-precipitation methods are not appropriate for...

Curcumin is the natural bio-active component of turmeric (Curcuma longa L.) with known therapeutic properties; nevertheless, its biological applications are limited due to its poor bioavailability. To overcome this limitation, curcumin was conjugated with silica nanoparticles. Curcumin was separated from turmeric by microwave-assisted extraction and silica nanoparticles were developed from rice...

The catalytic oxidation of toluene over copper oxide supported on natural diatomite was investigated. The catalyst was prepared by the wet impregnation method and characterized by using the Brunauer Emmett Teller (BET), field emission Scanning Electron Microscopy (FESEM), X-ray diffraction (XRD), X-ray fluorescence (XRF) and Temperature-programmed reduction (TPR) analysis. The highest catalytic ...

Information on the influence of impregnation of cementitious slurry at the soil-structure interface of bored cast in-situ foundation is inadequate in available literatures. Moreover, influence of such impregnation on negating the detrimental effects of smear zone, formed by construction tools, surrounding the borehole is also unknown. In classical foundation engineering, influences of smear and...

Fossil fuel depletion, increasing demands of energy, and harmful emission production led to do research on biofuels. In this research, biodiesel is developed by blending Jatropha Pongamia oil with the help magnetic stirrer-assisted transesterification process. Heterogeneous copper-doped titanium oxide catalyst was synthesized wet impregnation method. The characterized through XRD HRTEM analyses...

Drug elution properties of TiO(2) nanotube arrays have been largely investigated by means of solely macroscopic observations. Controversial elution performances have been reported so far and a clear comprehension of these phenomena is still missing as a consequence of a lack of molecular investigation methods. Here we propose a way to discern drug elution properties of nanotubes through the eva...
