主 题:energy storage N-doping plasma three-dimension
摘 要:Commonly used energy storage devices include stacked layers of active materials on two-dimensional sheets,and the limited specific surface area restricts the further development of energy ***-dimensional(3D)structures with high specific surface areas would improve device ***,we present a novel procedure to fabricate macroscopic,high-quality,nitrogen-doped,3D graphene/nanoparticle *** procedure includes vacuum filtration,freeze-drying,and plasma treatment,which can be further expanded for large-scale production of nitrogen-doped,graphene-based *** behavior of the supercapacitor is investigated using a typical nitrogen-doped graphene/Fe_(3)O_(4) nanoparticle 3D structure(NG/Fe_(3)O_(4)).Compared with 3D graphene/Fe_(3)O_(4) structures prepared by the traditional hydrothermal method,the NG/Fe_(3)O_(4) supercapacitor prepared by the present method has a 153%improvement in specific capacitance,and there is no obvious decrease in specific capacitance after 1000 *** present work provides a new and facile method to produce large-scale,3D,graphene-based materials with high specific capacitance for energy storage.
