Progress and perspectives of rapid Joule heating for the preparation of highly efficient catalysts

Abstract

Functional catalytic materials play an important role in the field of environmental, biological, energy fields, etc., wherein the unique properties can be endowed by virous synthesis strategy. However, the conventional catalysts preparation methods suffer from mild condition, prolong treatment and low energy transfer efficiency, thus leading to limited inherent nature of catalysts (such as: surface oxidation, agglomeration etc.). Recently, rapid Joule heating method, as novel synthesis method, has attracted widely attention due to the controllable kinetic conditions and eco-friendly operation, while the mechanisms, advantages and recent progress of such method has been concluded by few reviews. Herein, we systematically summarize basic fundamentals, fundamental parameters of Joule heating technique, as well as recent process in terms of effective modification strategies based on Joule heating. Meanwhile, the perspective suggestions and challenges for Joule heating methods on catalytic materials are put forward. This review provides new understanding for designing advanced catalytic materials.
