An efficient evaporation‐induced coating method combining microwave‐assisted hydrothermal transformation and annealing is developed to fabricate an ideal electrode material from composites with a layer of hydrous RuO 2 on mesoporous silica nanoparticles (MSNs), for a high‐performance supercapacitor. Total and RuO 2 ‐based specific capacitances are as high as 1125 and 2000 F g −1 , respectively.
