In our current study, supercritical water impregnation (SCWI) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. The method allows nano-particles to place on support surfaces in extremely dispersed conditions. The silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

paraloid-mg(oh)2 nanocomposites were synthesized via sonochemical method. nanostructures were characterized by xrd and sem. thermal stability behavior of paraloid filled with magnesium hydroxide was investigated by thermogravimetric analysis (tga). the influence of mg(oh)2 nanostructures on the flame retardancy of the paraloid matrix was studied using ul-94 analysis. our results show that the m...

This study demonstrates the use of a selective and sensitive voltammetric sensor for determination of acetaminophen (AC). This was  performed by modifying a glassy carbon electrode with composite film of poly(4-vinylpyridine) and graphene sheet (P4VP/GR-GCE). The redox peak currents of AC increased significantly at P4VP/GR-GCE. The result was achieved by the synergistic effect of combined elect...

Abstract Conventional synthetic methodologies mostly bar access to the fabrication of innovative silica- or metal oxide-based materials with an expanded property spectrum. However, nature represents inexhaustible source inspiration for synthesis multifunctional tailored attributes. Particularly low-energy catalytic pathways poriferan biosilicification, enzyme silicatein at their heart, have bee...

A novel method for the preparation of α-zirconium phosphate (ZrP) nanoparticles as an eco-friendly and recyclable heterogeneous catalyst was studied. Polyethylene glycol (PEG) was used as the organic matrix which produced a better dispersion of ZrP nanoparticles. The catalyst was characterized by several physico-chemical techniques such as ICP-OES, XRD, TPD-NH3, pyridine-FTIR, BET, FTIR, TGA, S...

Paraloid-Mg(OH)2 nanocomposites were synthesized via sonochemical method. Nanostructures were characterized by XRD and SEM. Thermal stability behavior of paraloid filled with magnesium hydroxide was investigated by thermogravimetric analysis (TGA). The influence of Mg(OH)2 nanostructures on the flame retardancy of the paraloid matrix was studied using UL-94 analysis. Our r...
