Hollow multishelled structure: Progress and prospects for next-generation energy and biomedical applications

Hollow structures have long served as a cornerstone of advanced materials innovation, linking nanoscale structural engineering to macroscopic functional performance.As a representative platform, hollow multishelled structure (HoMS) consists of no fewer than two shells with isolated quasi-enclosed internal cavities, forming an intriguing mesoscopic system.HoMS not only retains the merits of single-shelled hollow structure, but including large specific surface area, low density and high loading capacity.More significantly, they possess multiple adjustable shells and multiple adjustable inner cavities.Typically constructed from assembled nanoparticles, the shells of HoMS are interconnected via channels, gases, liquid or other cores, endowing them with a cell-like hierarchical architecture.Notably, their distinctive temporal-spatial ordering property renders HoMS irreplaceable in pivotal applications, including catalytic reactions, sustained drug delivery, and energy storage [1-3].Since research interest in HoMS was began in 2004, the unique structure has evolved for more than two decades to date.In pioneering research work, Wang's group has developed a universal sequential templating strategy (STA) in 2009 [4].Furthermore, we have revealed Page 1 of 5 https://mc03.manuscriptcentral.
