In this work, Jet nebulizer technique was used to prepare thin films of CuO (1%) doped with ZnO-carbon nanotubes (CuO/ZnO/CNTs). The morphology, surface roughness, pattern, and elemental composition the were examined by X-ray diffraction, scanning electron microscopy, atomic force Raman analysis, PL emission transmission respectively. photocatalytic activity pure CuO/ZnO/CNTs using rate degradation Rhodamine-B (RhB) under effect UV-B irradiation. UV–Vis analysis revealed that average crystal...
Biosorption using natural waste has emerged as a potential and promising strategy for removal of toxic dyes from wastewaters in comparison to conventional ones. Herein, the Codium decorticatum alga (CDA) was biologically identified used biosorbent anionic cationic aqueous solutions. SEM analysis showed rough surface with an irregular edge shape while hydroxyl, amine, sulfur carboxyl functional groups were FTIR analysis. TGA/DTG confirmed stability CDA adsorption process. Batch studies...
This study focuses on the removal of phenol from aqueous media using Agouraï clay (Fes-Meknes-Morocco region) and Geulmima (Draa Tafilalet region). The characterization by Fourier Transform Infrared (FTIR) Spectroscopy, X-ray diffraction (XRD), N2 adsorption (BET), Scanning Electron Microscopy (SEM), Thermogravimetric differential thermal analysis (DTA/GTA) indicates that it is mainly composed quartz, kaolinite, illite. results showed raw Clay Agourai (RCA) (RCG) adsorbed very quickly...
The production of cobalt oxide nanoparticles and their use in the adsorption methylene blue (MB) from solution is described paper. X-ray diffraction patterns show that synthesized have a crystalline cubic structure. study onto involved determining contact time initial concentration MB on adsorbent. kinetics were analyzed using two kinetic models (pseudo-first order pseudo-second order), pseudo-second-order model was found to be most appropriate for describing behavior adsorption. This...
Controlled titanium alkoxide mineralization in the presence of phosphonated, dendrimeric nano-building blocks provides a new family hierarchically porous dendrimer-bridged dioxide materials.
The scarcity of low temperature syntheses anatase nanocrystals prompted us to explore the use surface-reactive fourth generation phosphorus-dendrimers as molds control nucleation and growth titanium-oxo-species during sol-gel mineralization process. Unexpectedly, dendritic medium provides at temperature, discrete (4.8 5.2 nm in size), marked contrast routinely obtained amorphous titanium dioxide phase under standard conditions. Upon thermal treatment, heteroatom migration from branches...
Hitherto, the field of nanomedicine has been overwhelmingly dominated by use mesoporous organosilicas compared to their metal oxide congeners. Despite remarkable reactivity, titanium oxide-based materials have seldom evaluated and little knowledge gained with respect "structure-biological activity" relationship. Herein, a fruitful association phosphorus dendrimers (both "ammonium-terminated" "phosphonate-terminated") dioxide performed means sol-gel process, resulting in dendrimer-coated...
The sol-gel co-condensation of organo-phosphonates to titanium alkoxides enables access novel organic-inorganic hybrids based on phosphonate-bridged dioxide. In this contribution, we bring new perspectives the long established mineralization alkoxide species, by harnessing virtues well-designed phosphonate-terminated phosphorus dendrimers as reactive amphiphilic nanoreactor, confined medium and cross-linked template generate discrete crystalline anatase nanoparticles at low temperature (T =...
Photoactive viologen fragments were covalently embedded within the material framework during self-assembly and sol-gel polymerisation of phosphonate-terminated dendrimers soluble titanium-oxo-species. The resulting porous anisotropic phosphonate-bridged-crystalline anatase materials serve as new hosts to disperse stabilize small gold nanoparticles.
Novel silicates were prepared by using silylated natural fatty acids (derived from triglyceride renewable oils) as co-condensing reagents in presence of tetraethyl orthosilicate (TEOS) and the triblock copolymer, pluronic P123, a structure directing agent. A series carboxylic acid functionalized SBA-15-type mesoporous obtained with tunable nanoscopic order reactive functional groups that allow conjugation amino probes peptide coupling. Photophysical studies covalently linked aminopyrene...
The lamellar and nanostructured manganese oxide materials were chemically synthesized by soft non-toxic methods. showed a monophasic character, symptomatic morphologies, as well the predominance of mesoporous structure. removal heavy metals Cd(II) Pb(II) Na-MnO2, Urchin-MnO2 Cocoon-MnO2 according to mineral structure nature sites also studied. Kinetically, material Na-MnO2 was most efficient three which had more vacancies in MnO6 layers space between layers. nanomaterials could exchange with...
Abstract Highly metal oxide heterostructures are well known for their high effectiveness toward the growth of many pathogens. ZnO was widely studied this purpose; however, doping effect on its antibacterial properties is still not satisfactory. In context, present work aimed to prepare a series mesoporous doped with different neodymium (Nd) loading using ball‐milling method and examine activities against gram‐positive gram‐negative All as‐synthesized materials were characterized by X‐ray...
