Nano-sized protonated ZSM–5 ( H-ZSM-5nanozeolite) was successfully synthesized by the hydrothermal method using the bagasse ash (BGA) as a new silica source. Cultivated BGA in the south of the Caspian Sea (Mazandaran province, Iran) was used for extracting silica powder. H-ZSM-5 was characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electronic microscopy (SEM...

AgAl2O3 nanocomposite were synthesized by solution combustion Technique using ammonium carbonate as a new fuel under simultaneous combustion of alumina and silver particles condition. Samples prepared with different amount of silver, were characterized by XRD, BET, SEM and optical Absorption measurements. XRD analysis was used to determine the change in phase and size of the synthesized n...

Three activated carbons are synthesized in a rotary reactor at different activation times. The adsorption isotherms of the samples are measured The pore size distribution of the samples is determined using combined Saito and Foley method, BJH method. An average potential function has been determined inside the cylindrical pores. The effect of activation time on the pore size distribution sample...

In the present work, Iranian natural zeolite particles (NZ) as an abundant and low-cost resource were modified by chemical covalent attachments of commercially available stearic acid (SA) with tunable hydrophobic/hydrophilic properties. The versatile, simple, and green technique of mechanogriding was performed for the hydrophobic derivatisation of NZ. The NZ and as-prepared modified particles w...

In this study, the nanoporous γ-alumina catalysts were prepared by the sol-gel method using hydrolysis of aluminum isopropoxide in the presence of TX-100 or gelatin/TX-100 mixture. Catalysts were characterized by XRD, FT-IR, TEM, BET-BJH and N2 adsorption-desorption isotherms. To investigate reactivity and selectivity of the synthesized catalysts, dehydration reaction of 2-octanol was carried o...

In this research, Ni(8%)/TiO2/Zeolite NaX nanophotocatalyst was synthesized andevaluated as a desulfurizer catalyst from hydrophane 10 base oil. Various tests,including X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Analysis (EDXA), Transmission Electron Microscopy (TEM), AtomicForce Microscopy (AFM), and BET/BJH were used to evaluat...

The successful synthesis of AMn2O4 (A = Co, Cu and Ni) spinels via solution combustion was achieved in less time than other methods. All catalysts with the same nitrate fuel ratio were used oxidation toluene relationship between their proprieties activities investigated. Among all, nickel manganite exhibited most promising activity by changing ratio, it sought to obtain appropriate structure fo...

This study presents the results of a process thermography and convective drying retention substance bentonite used in production nanocatalysts based on Zol-gel technology. The using energy convex-EHFEF EMF (extremely high-frequency electromagnetic field) preparation nanocatalystsfrom retaining is illuminated by derivatogram from Navbahor deposit determined thermographic method. determination po...
