Abstract:Compound Zn2SnO4 was synthesized by a hydrothermal method in which SnCl4 · 5H2O, ZnCl2 and N2H4 · H2O were used as reactants. Composite Zn2SnO4/C was then synthesized through a carbothermic reduction process using the as-prepared Zn2SnO4 and glucose as reactants. Comparing to the pure Zn2SnO4, some improved electrochemical properties were obtained for composite Zn2SnO4/C. When doped with 15% glucose, the composite Zn2SnO4/C showed the best electrochemical performance. Its first discharge capacity was about 1500 mA h g−1, with a capacity retain of 500 mA h g−1 in the 40th cycle at a constant current density of 100 mA/g in the voltage range of 0.05–3.0 V. There were also some differences displayed in their cyclic voltammogram.
