Abstract
SnO2/graphite oxide/g-C3N4 composite was synthesized by hydrothermally growing SnO2 nanosheets on graphite oxide/g-C3N4 using tin dichloride and mercapto acetic acid as tin source and structure-directing agent for SnO2 nanosheets, respectively. For comparison, SnO2/graphite oxide and SnO2/g-C3N4 composites were prepared with the same procedure except different supports. The obtained composites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, thermogravimetric-differential thermal analysis and electrochemical properties. The results show that the SnO2/graphite oxide/g-C3N4 composite with the graphite oxide/g-C3N4 support enhanced reversible capacity and cycling performance for lithium storage.
