Metal Organic Framework (MOF) is a material that serves as photocatalyst for decomposing methylene blue pollutant. MOF can be constructed using several kinds of synthetic methods. This study aims to determine the alternative efficient and eco-friendly synthesis method isonicotinic acid-modulated chromium perylene 3,4,9,10-tetracharboxylate (Cr-PTC-HIna) solvothermal, hydrothermal, sonochemical,...
A series of MFI-type aluminosilicate catalysts with ultasound-assisted rapid hydrothermal and conventional high temperature methods were synthesized at temperatures 250 300°C. The pure MFI framework was obtained when sonochemical method used prior to the conditions 250°C 3h. samples characterized by XRD, FESEM, BET-BJH, FTIR, TPD-NH 3 TG/DTG analyses. morphological analysis indicated coffin sha...
This review covers sonochemical fabrication of polymer nanocomposites. In addition to its application to the synthesis of various polymeric systems, due to its powerful efficiency, sonochemistry has been widely used not only as the assistant of dispersion for nanomaterials such as carbon nanotubes (CNT) and organophillic clay, but also as a special initiator to enhance polymerization for fabric...
in this investigation, we report facile synthesis of cadmium(ii)-thioacetamide nanocomposites in the presence and absence of polyvinyl alcohol under ultrasonic irradiations, using cadmium acetate dihydrate (cd(ch3coo)2.2h2o), potassium iodide (ki), thioacetamide (taa, ch3csnh2), and polyvinyl alcohol (pva) as the starting materials. results show that in the presence of polyvinyl alcohol size...
a novel nano – sized manganese (ii) coordination polymer, [{mn(ncs)2(l)(h2o)2}(l)]n , (1) (l- = 4,4'-bipyridine), have been synthesized by a sonochemical process and characterized by scanning electron microscopy (sem), x-ray diffraction (xrd), ir spectroscopy and elemental analysis. direct calcination of the single crystals and nano-sized compound 1 at 400 0c under air atmosphere yields...
Two-dimensional (2D) liquid–metal (LM) heterointerfaces with their tunable physicochemical characteristics are emerging platforms for the development of multifunctional hybrid nanostructures numerous functional applications. From this perspective, functionalization LM galinstan nanoparticles (NPs) crystalline nanodomains is a promising approach toward synthesis novel 2D unprecedented properties...
