“…Since fullerenes, nanotubes, and graphene were discovered successively, carbon materials with different dimensional configurations have always been one of the research hotspots because of their unique physical and chemical properties and extensive applications in various fields. − As a new member of the carbon materials family, the zero-dimensional hollow carbon spheres with carbonaceous shells (polymer or carbon) and adjustable interior voids have attracted more and more attention in the past decade, owing to their unique architecture features such as huge surface area, low specific density, excellent stability, and enough capacity for integrating with other components. − It is proved that hollow carbon spheres and derived composites exhibit prominent performance in heterogeneous catalysis, adsorption and separation, electrochemistry, energy storage, and so on. ,− …”
