In this study, the Ni(II) Schiff base/SBA-15 catalyst was successfully synthesized and characterized by employing FT-IR, XRD, TGA, EDX, ICP-OES, TEM, SEM analysis. addition, BJH BET techniques were used to determine specific surface area, pore size, volume of catalyst, which 538 m2 g−1, 6 nm, 1.01 cm3 correspondingly. Under favorable conditions, we have designed a one-pot multicomponent reactio...

The adsorption capacities of two synthesized zeolites (crystalline ZSM-5 and semi-crystalline faujasite Y) for a mixture indole, quinoline carbazole were studied. different samples obtained show crystalline degree, mesoporosity Si/Al ratios. synthesis procedure is based on the simultaneous depolymerization high surface area silica, such as rice hull ashes (RHA), zeolite, clinoptilolite or fauja...

The aim of this study is to investigate the oxalic acid activation bentonites containing different types smectites, analyse their surface modification as a function concentration and create good quality bleaching earths. In particular, two bentonite samples (one aluminum one ferruginous smectite), after being characterized through XRD, XRF FT-IR analysis, are treated with at 0.5, 0.7 1 M. Their...

Sugar cane molasses has proved cohesive and excellent performance on soil aggregates (fine particles). However, the microstructure of consolidated by is not yet subjected to research. The analysis results sample without (0%) samples at 8%, 12%, 16% show that acts structure clayey fine developing its airy matrix type (sample a qualified type, more solid. Consolidated molasses). We also observe p...

Abstract The adsorption process is more suitable because the costs required are not too expensive and will cause new contaminants. Currently, research being promoted on use of alternative adsorbents derived from nature. Natural in addition to having good ability, also economical. biosorbent pineapple leaves (Ananas comosus L) which had previously been carried out with carbonation, activation, c...

TiO2 nanomaterials with controlled morphologies have attracted extensive interest because of potential applications in solar energy conversion, environmental cleanup and hydrogen generation. Nanoscale titanium dioxides have been produced as nanotubes, nanosheets, nanowires and mesoporous microspheres by a variety of approaches. Among the various nanomaterials, mesoporous microspheres have drawn...

Hexavalent chromium is one of the most hazardous contaminants that threaten environment. The present research work involves synthesis Graphene Oxide/Zinc molybdate (GO/ZM) nanocomposite by wet chemical route. structure and morphology synthesized samples were analysed various characterization techniques such as X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), UV-Vis Spect...

Abstract Six silica-supported phosphotungstic acid catalysts (PTA/SiO 2 ) of different composition (20–70 wt% PTA content) have been synthesized and characterized by elemental analysis, BET, BJH, NH 3 -TPD methods, FT-IR spectroscopy adsorbed pyridine 1 H MAS NMR techniques. The new composite were first applied in the Friedel–Crafts alkylation toluene with 1-octene as a benchmark process under ...

Hexagonal mesoporous silica (SBA-15) was prepared and then functionalized by(3-mercaptopropyl)trimethoxysilane. The obtained 3-mercaptopropyl functionalized SBA-15 (SBA-Pr-SH) was then oxidized using H2O2 in methanol under an acidic condition to give sulfonic acid functionalized mesoporous silica (SBA-Pr-SO3H). Th...

In this study, green or eco-friendly synthesis of TiO2 nanoparticles (NPs) was performed by using the aqueous extract of Acanthophyllum laxiusculum. The plant genus Acanthophyllumis one of the natural sources rich in nonionic surface active agents known as saponins. Sol-gel method as one of the most common techniques widely used in nano-field was applied to synthesize the titanium dioxide nanop...
