Abstract:SnO2 microspheres were prepared by an ion exchange technique using a cationic resin as template. The material obtained by calcination was investigated by several techniques and showed singular properties. Removal of the polymeric matrix led to hierarchical layers of hollow SnO2 microspheres with mean particle size of 43 μm and surface area of 27.8 m2 g−1. The Matryoshka‐like structure showed 3 to 5 stacked shells that were comprised by aggregated nanocrystals of 19.6 nm as building blocks. The crystallization … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
