About this Research Topic
Microwave-mediated heating technology, based on molecular-level heating, has gained a great deal of attention in academia and industry. Use of microwave irradiation to “accelerate” synthesis reaction, pyrolysis and materials fabrication, has been the subject of considerable speculation and discussion recently. Specific microwave effects are caused by the uniqueness of the microwave dielectric heating mechanisms including, for example:
- The superheating effect of solvents at atmospheric pressure;
- The selective heating of strongly microwave-absorbing solid catalysts or reagents in a less polar reaction medium;
- The formation of “molecular radiators” by direct coupling of microwave energy to specific reagents in homogeneous solution;
- The elimination of wall effects caused by inverted temperature gradients.
This Research Topic on microwave-mediated catalysis mainly covers the current research in developing rapid, robust, and selective microwave-assisted transition-metal-catalyzed homogeneous/heterogeneous/enzymatic catalysis reactions. Emphasis will be put on the applications, including selective organic synthesis, pyrolysis reaction, and materials fabrications. Green chemistry was developed to meet increasing demands for environmentally-benign chemical processes. We believe the combination of catalysis induced by microwave irradiation will be of importance in green chemistry and chemical engineering fields. Original research articles, reviews, and perspectives are all welcome. Potential topics include, but are not limited to:
- Preparation of heterogeneous catalysis materials that will response with microwave photon through the incorporation of catalytic active site such as metal, acid, etc;
- New microwave-accelerated homogeneous reactions and their mechanisms;
- Microwave activation of enzymatic catalysis reaction;
- Development of applications for microwave catalytic processes such as pyrolysis, material fabrication, chemistry reaction, etc.
