The nanoscale effect enables the unique magnetic,optical,thermal and electrical properties of nanostructured materials and has attracted extensive investigation for applications in catalysis,biomedicine,sensors,and energy storage and conversion.The widely used synthesis methods,such as traditional hydrothermal reaction and calcination,are bulk heating processes based on thermal radiation.Differing from traditional heating methods,non-thermal radiation heating technique is a local heating mode.In this regard,this review summarizes various non-thermal radiation heating methods for synthesis of nanomaterials,including microwave heating,induction heating,Joule heating,laser heating and electron beam heating.The advantages and disadvantages of these non-thermal radiation heating methods for the synthesis of nanomaterials are compared and discussed.Finally,the future development and challenges of non-thermal radiation heating method for potential synthesis of nanomaterials are discussed.
