Oxidation of bisphenol-A (BPA) was investigated using a sonophoto Fenton-like hybrid process under visible light irradiation in the presence of iron-containing perovskite LaFeO3 catalysts. For this purpose, firstly the perovskite catalyst (LaFeO3) was prepared by the sol-gel method and calcined at different temperatures (500, 700, and 800 ◦C). The prepared catalysts were characterized using XRD...

In this research, initially, the sol-gel method was employed to produce γ-alumina and TiO2 catalysts with core-shell structure. Iron (III) was used as a dopant. The newlyproduced core-shells were Fe/TiO2// Fe/ γ-Al2O3 (FTFA). Sulfonated cobalt phthalocyanine was used as a dye pollutant in Merox process. By doping Fe in TiO2 catalyst, the ef...

Here, metal nanoparticles were synthesized by chemical reduction of the corresponding metal salts in the presence of chitosan polymer. Binary and ternary metallic-chitosan Pt-Fe-CH, Pt-Co-CH and Pt-Fe-Co-CH nanocomposites were prepared. Transmission electron microscopy images and UV–Vis spectra of the nanocomposites confirmed the presence of the metal nanoparticles. The electrocatalytic activit...

BACKGROUND Anomalous use of antibiotics and their entrance into the environment have increased concerns around the world. These compounds enter the environment through an incomplete metabolism and a considerable amount of them cannot be removed using conventional wastewater treatment. Therefore, the main objectives of this research are evaluation of the feasibility of using ultraviolet radiatio...

Honeycomb cordierite-based Mn–Ce/Al2O3 catalysts were prepared by the impregnation method and used for low-temperature selective catalytic reduction (SCR) of NOx with NH3, with and without SO2 and/or H2O in a homemade fixed-bed tubular reactor. The catalyst reached nearly 80% NOx conversion at 100 ◦C in the absence of SO2. However, SO2 reduces the catalytic activity (80% to 72%) of the honeycom...

background: pre-chlorination of raw water containing natural organic matters may lead to forming harmful disinfection by-products such as trihalomethanes (thms), the measurement of which needs expensive advanced analytical instruments. this study was conducted to anticipate thms formation potential in bandar abbas drinking water system using cheap and simple experiments and a mathematical model...

In this study, we report removal of Diclofenac (DCF) through heterogeneous Fenton process using Fe-ZSM-5 catalyst. The parent catalyst was prepared by hydrothermal technique. Fe species were introduced by wet impregnation. Characterization of the catalysts was carried out using XRD, FT-IR, FE-SEM, N2 adsorption-desorption, NH3-TPD, and acidimetric-alkalimetric titration. The bimetallic catalyst...

The catalyst containing 80%Co/20%Ce/15wt%SiO2 was prepared using fusion procedure and studied for the conversion of synthesis gas to light olefins. The effect of a range of operating variables such as the pressure, temperature and H2/CO molar feed ratio on the catalytic performance of fused catalyst was investigated. It was found that the best operating conditions are H2/CO=2/1, T=350 ̊C and P=2...

A novel Mo-promoted Ce-Zr mixed oxide catalyst prepared by a homogeneous precipitation method was used for the selective catalytic reduction (SCR) of NO(x) with NH3. The optimal catalyst showed high NH3-SCR activity, SO2/H2O durability, and thermal stability under test conditions. The addition of Mo inhibited growth of the CeO2 particle size, improved the redox ability, and increased the amount...
