Microwave chemistry for inorganic nanomaterials synthesis

Abstract

This Feature Article gives an overview of microwave-assisted liquid phase routes to inorganic nanomaterials. Whereas microwave chemistry is a well-established technique in organic synthesis, its use in inorganic nanomaterials' synthesis is still at the beginning and far away from having reached its full potential. However, the rapidly growing number of publications in this field suggests that microwave chemistry will play an outstanding role in the broad field of Nanoscience and Nanotechnology. This article is not meant to give an exhaustive overview of all nanomaterials synthesized by the microwave technique, but to discuss the new opportunities that arise as a result of the unique features of microwave chemistry. Principles, advantages and limitations of microwave chemistry are introduced, its application in the synthesis of different classes of functional nanomaterials is discussed, and finally expected benefits for nanomaterials' synthesis are elaborated.

Fingerprints of short-range and long-range structure in BaZr1−xHfxO3 solid solutions: an experimental and theoretical study

“…MAH method has demonstrated its efficiency in the synthesis of materials with new and/or intensified properties [17][18][19][20][21] . The advantages of this synthesis method are the strong reduction over the time and temperatures even compared with hydrothermal and/or solvothermal conventional methodologies 22,23 .…”

Microwave enhanced silica encapsulation of magnetic nanoparticles

“…Microwave technology has been extensively employed in organic synthesis 19,20 and nanomaterial fabrication [21][22][23][24][25] due to its many advantages, such as increased reaction rates, ability to use mild reaction conditions, and high product yield. 19 In recent years, microwave approaches have been employed for silica encapsulation of bare non-magnetic nanomaterials that are water dispersible originally.…”

Green approach for the synthesis and characterization of ZrSnO4 nanopowder

“…The functional properties can be tuned by modifying the size, shape and composition of the synthon along by studying state of art of the synthetic method with pH control which helps to design a device for their technological applications with synergic effects to control the nucleation and its growth. Understanding the nucleation and growth process by self-assembling helps to integrate functional structures via optimizing hydrolysis and kinetic process based on electro-negativity of metal ion (Klein 1988;Brinker and Scherer 1990;Sakka 2004;Szafert et al 2008;Grado-Caffaro 2008;Bilecka and Niederberger 2010;Bang and Suslick 2010;Liu et al 2011;Hassan et al 2012;Precht and Campbel 2013;An and Soorrjai 2015).…”

“…Bimetallic oxide exhibits novel physico-chemical properties that can be tailored with composition, size and atomic ordering. Metal ion plays a crucial role in balancing the thermodynamic-kinetic parameters to control functional behavior due to its coordination with metal ions and also tuning of surface morphology leads to the formation of nanostructure material with high performance (Klein 1988;Brinker and Scherer 1990;Kessler 2003;Sakka 2004;Szafert et al 2008;Bilecka and Niederberger 2010;Hassan et al 2012;Precht and Campbel 2013;An and Soorrjai 2015). During synthesis, we focused the phase separation with non-aggregated particles by retaining stoichiometric ratio under control.…”
