Sonochemical catalysis as a unique strategy for the fabrication of nano-/micro-structured inorganics

Abstract

Ultrasound-assisted approaches, as an important trend in the material synthesis, have emerged in designing and creating nano/micro- structures. Here the review simply presents the basic principles of ultrasound irradiation including...

Accelerated Redox Reaction of Hydrogen Peroxide by Employing Locally Concentrated State of Copper Catalysts on Polymer Chain

“…The molecules that generate highly toxic hydroxyl radicals are applicable in designing antitumor drugs and antibiotics. [ 7,9,10 ] Thus, to verify the virtue of constructing pDPACu(II)MA for such applications, its utility as antibiotics against Escherichia coli was investigated. Because bacteria are more likely to exhibit resistance mechanisms against the simple derivatives of already known and used antibiotics, a novel methodology is always required to design antibiotics.…”

“…[ 5,6 ] The generated hydroxyl radical finds application not only in the field of organic chemistry, but also in drug discovery research due to its anticancer and antibacterial effects. [ 5,7–9 ] As copper in aqueous medium usually exists as copper(II) under normal pressure and temperature conditions, copper(II) should first be reduced to copper(I). Although hydrogen peroxide can act as a reductant, the copper(II) reduction with hydrogen peroxide (Scheme 1a,ii) is not feasible compared to the copper(I) oxidation with hydrogen peroxide (Scheme 1a,i).…”

A power-triggered preparation strategy of nano-structured inorganics: sonosynthesis

“…In fact, the structure, size, stability and activity of inorganicsbased hybrid nanomaterials are important to both the quality of properties and the acceptability of applications, so that the relevant research results or viewpoints have been reviewed in detail in other papers. [167][168][169][170][171][172][173]…”

Greener organic synthetic methods: Sonochemistry and heterogeneous catalysis promoted multicomponent reactions

“…As in other chemical processes, sonochemistry also involves the dissociation and formation of chemical bonds [74] . When ultrasonic waves with frequencies above 20 kHz are radiated in a liquid, they can break chemical bonds (sonolysis) and produce free radicals, which will be able to promote a series of chemical transformations.…”
