In recent years the synthesis of nanomaterials has become a major topic in scientific research. In different chemical disciplines numerous methods for preparing tailored nanomaterials with individual properties have been investigated extensively. Microwave irradiation has proven beneficial since slight changes in reaction temperature and/or time will result in reproducible structures with novel and desired performance properties. In most of the cases microwave‐mediated reaction times are substantially shorter, and the subsequent particle size distributions are much more defined when compared to conventional methods. In this presentation, we will illustrate several published examples of how microwave‐assisted techniques can be applied towards the successful synthesis of a wide variety of nanomaterials. Emphasis will be placed on the unique operating parameters of dedicated microwave reactors, and the subsequent positive influence on nanomaterial structures.
