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...

A set of styrene-ethylene-butylene-styrene triblock copolymer (SEBS) membranes with 10 or 25 wt% divinyl-benzene (DVB) as a crosslinking agent were prepared and validated. Physicochemical characterization revealed suitable hydrolytic thermal stability photo-crosslinked containing DVB post-sulfonated. These compositions evaluated in H2/O2 single cells, electrical proton conductivities furtherly ...

Chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. This work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various dead-end pore parameters (such as opening, depth, aspect ratio, and orientation). Using glas...

A green methodology for the development of the synthesis of dihydropyrimidinones via a clean multi-component Biginelli reaction by using cyclohexane-1,4-diyl bis (hydrogen sulfate) (CDBH) as an effective catalyst in water and solvent-free conditions was reported. This sulfonated catalyst is an efficient and environmentally benign homogeneous catalysts which characterized by using different tech...

Sulfonated sPPFS-b-PBuA diblock and statistical copolymers based on 2,3,4,5,6-pentafluorostyrene PFS butyl acrylate BuA were elaborated for Proton Exchange Membrane Water Electrolyser (PEMWE) purposes. The block (BCP) synthetized by Nitroxide Mediated Polymerization NMP, a controlled radical polymerization technique that yields well-defined molar mass low dispersity material. These diblock-copo...
