Scientists propose new properties in hollow multi
A new study led by Prof. Wang Dan from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences proposes a novel concept of temporal-spatial ordering and dynamic smart behavior in HoMSs. It was published in Nature Reviews Chemistry on Feb. 11.
Unlike the single shell hollow sphere or nanoparticles, HoMS has potential applications in fields ranging from energy conversion and storage to catalysis, since it avoids easy agglomeration of nanoparticles, maintains the advantage of effective surface area, and benefits the mass transmission.
In the first phase of their work, the group developed a facile sequential templating approach (STA) for the fabrication of HoMS. This approach realized precise control of the shell number, thickness, distance, and facet exposure, thus modulating surface properties and the interface of HoMS materials.
Specifically, multishells separate space into various, relatively isolated subspaces. At the same time, the heterogeneous pores on each shell facilitate the transmission of small molecules.标签：
