Heat‐Up Process: Road to Synthesizing Monodisperse Nanoparticles

Abstract

AbstractLarge‐scale synthesis of monodisperse nanoparticles is highly desirable for practical applications of nanoparticles in various fields of emerging technology. Among colloidal synthetic routes of monodisperse nanoparticles, heat‐up process, which involves a gradual heating of precursor solution in a batch reactor, has received utmost interest after its successful size‐controlled synthesis of various kinds of nanoparticles. In this essay, we discuss the fundamental research regarding the synthesis of monodisperse nanoparticles and describe how researchers developed the heat‐up process. The mechanistic insights into this synthetic method and the discovery of size‐dependent properties of monodisperse nanoparticles are also presented. We further emphasize its great impacts on utilizing monodisperse nanoparticles synthesized via the heat‐up process for biomedical technology, energy conversion and storage devices, as well as electronic and optoelectronic devices.
