Magnetite nanoparticles (Fe₃O₄) represent the most promising materials in medical applications. To favor high-drug or enzyme loading on the nanoparticles, they are incorporated into mesoporous materials to form a hybrid support with the consequent reduction of magnetization saturation. The direct synthesis of mesoporous structures appears to be of interest. To this end, magnetite nanoparticles ...

a novel sulfur nanocomposite was fabricated based on graphitic mesoporous carbon.the graphitic mesoporous carbon was synthesized using sucrose as carbon precursor, nano caco3 as hard template and nickel nitrate as graphitization catalyst. the structural properties of the prepared material were characterized using powder x-ray diffraction (xrd), n2-adsorption/desorption and scanning electron mic...

Highly ordered mesoporous silver, which exhibits well-defined mesopores, high surface area and pore volume, has been successfully obtained using a cubic mesoporous silica, KIT-6, with controlled surface hydrophobicity as the hard template.

Spinel Li4Ti5O12 (LTO) and reduced graphene oxide (rGO) are attractive anode materials for lithium-ion batteries (LIBs) because of their unique electrochemical properties. Herein, we report a facile one-step hydrothermal method in preparation of a nanocomposite anode consisting of well-dispersed mesoporous LTO particles onto rGO. An important reaction step involves glucose as a novel linker age...

Surface of mesostructured silica, KIT-6, was modified by grafting 3-aminopropyl-triethoxysilane (APTES) to have the positive charge, and thus, to provide sites for the immobilization of H3PW12O40 (PW12).  This modified-nanosized mesoporous silica (PW12-APTES@ KIT-6) was characterized by FTIR, XRD, BET and TEM. The oxidation of sulfides occurs effectively and selectively with H2O2 as the oxidant...

Background: Multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. A rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles. Objectives: Herein, we report on a simple approach for the synthesis of m...

Mesoporous TiO2/reduced graphene oxide/Ag (TiO2/RGO/Ag) ternary nanocomposite with an effective electron transfer pathway is obtained by an electrostatic self-assembly method and photo-assisted treatment. Compared with bare mesoporous TiO2 (MT) and mesoporous TiO2/RGO (MTG), the ternary mesoporous TiO2/RGO/Ag (MTGA) nanocomposite exhibited superior photocatalytic performance for the degradation...
