Mesoporous carbon hollow sphere with dandelion‐like radial‐hierarchy for high‐performance supercapacitors

Ordered mesoporous carbons (OMCs) possess great advantages, such as large surface area, uniform pore distribution, high porosity, and physical and chemical stability. However, the monotonic and long porous channels in OMCs hinder their further application, especially in energy storage. Here, we synthesized mesoporous carbon hollow spheres (MCHSs) with a “Dual-templating method” using dandelion-like silica spheres (DSSs) as the template. Through...
