One-step preparation and characterization of nanosized Sn–CN materials

Abstract

Sn-based N-doped carbon composites (Sn–CN) were simply fabricated via a one-pot thermal reaction. This experiment uses SnCl4·5H2O, resorcinol, formaldehyde and melamine as raw material. In order to improving the theoretical capacitance and cycle performance, the tin-carbon composite material can be modified to obtain an excellent electrochemical properties. Meanwhile, the introduction of an appropriate amount of nitrogen can increase the electrical conductivity of the material. This article mainly analyzes the properties of the material from X-ray diffraction, scanning electron microscopy and cyclic voltammetry curve.
