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,...

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...

Sonochemical synthesis was used to create novel solar light active Mg-doped CuO nanoparticles. Through a chemical impregnation method, the produced nanomaterial changed with PVA (polyvinylalcohol). The optical properties, crystal structure, and surface morphologies of synthesized nanomaterials were probed by UV-visible spectroscopy (UV-vis-DRS), Fourier transform infrared (FT-IR), Raman spectro...

Background and purpose: Cyanide is a species of high toxicity that is found mostly in industrial effluents such as electroplating, metal mining, metallurgy and metal cleaning processes. Entrance of it to existing environment contains a hazardous to health. The purpose of this study was to compare efficiency of both sonochemical and sonochemical / hydrogen peroxide processes for cyanide rem...

A sonochemical process has been developed for the insertion of tin nanoparticles into mesoporous carbon, giving a product which was used as a building block for the anode of a rechargeable Li battery; the electrode could deliver a reversible capacity of 400 mAh gr(-1)(C + Sn) at 100% cycling efficiency, which is higher than that of graphite electrodes.

We report the sonochemical synthesis of copper(I) hydride (CuH) by the ultrasonic irradiation of a copper(II) aqueous solution. A reaction mechanism based on the reduction of copper(II) by the ultrasound-generated hydrogen atoms is discussed. To the best of our knowledge, this is the first time that a metal hydride has been synthesized through sonochemistry.

A facile, versatile, and one-pot sonochemical synthesis of polydopamine (PDA)-nanocapsules from dopamine is reported. The nanocapsules (227 ± 25 nm) can encapsulate hydrophobic substances while retaining the reactivity of PDA toward nucleophilic reactions, enabling facile surface modification for different applications. PDA nanocapsules are nontoxic to mammalian cells while Cu-containing PDA ca...
