Confined nanospace pyrolysis: A versatile strategy to create hollow structured porous carbons

Confined nanospace pyrolysis (CNP) has attracted increasing attention as a general strategy to prepare task-specific hollow structured porous carbons (HSPCs) in the past decade. The unique advantages of the CNP strategy include its outstanding ability in control of the monodispersity, porosity and internal cavity of HSPCs. As a consequence, the obtained HSPCs perform exceptionally well in applications where a high dispersibility and tailored cavity are particularly required, such as drug delivery, energy storage, catalysis and so on. In this review, the fundamentals of the CNP strategy and its advances in structural alternation is first summarized, then typical applications are discussed by exemplifying specific synthesis examples. In addition, this review offers insights into future developments for advanced task-specific hollow structured porous materials prepared by the CNP strategy.
