Nitrogen-Doped Mesoporous Carbon Microspheres by Spray Drying-Vapor Deposition for High-Performance Supercapacitor

Blog Article

Nitrogen-doped mesoporous carbon microspheres have been Foam Tipped Cleaning Swabs successfully synthesized via a spray drying-vapor deposition method for the first time, using commercial Ludox silica nanoparticles as hard templates.Compared to freeze-drying and air-drying methods, mesoporous carbon with a higher packing density can be achieved through the spray drying method.Vapor deposition of polypyrrole followed by carbonization and etching is beneficial for the generation of ultra-thin carbon network.The mesoporous carbon microspheres possess a mesopore-dominate (95%) high surface area of 1528 m2 g−1, a wall thickness of 1.8 nm, and a nitrogen content of 8 at% in the framework.

Benefiting from the increased apparent density, high mesopore surface area, and considerable nitrogen doping, the resultant mesoporous carbon microspheres show superior gravimetric/volumetric capacitance of 533.6 F g−1 and 208.1 F cm−3, good rate performance and excellent cycling stability in electric Toy Cars double-layer capacitors.
