An ordered mesoporous network consisting of carbon‐coated ultrasmall SnO2 nanoparticles with enhanced Lithium storage

An unique ordered mesoporous network consisting of carbon‐coated SnO2 nanoparticles (NPs) is developed by a facile self‐assemble strategy via a solvethermal route in which employs N,N‐dimethylformamide/H2O as mixture solvent and polyvinyl pyrrolidone as barrier agent and carbon source. The SnO2‐NPs with an uniform dimension of ~5 nm are observed to interconnect with each other, and assemble into high‐compact blocks where abundant mesopores with an average diameter of ~4 nm are found throughout the body. The carbon coating with a thickness of
