Gradient-temperature hydrothermal fabrication of hierarchical Zn2SnO4 hollow boxes stimulated by thermodynamic phase transformation†
Abstract
We develop a facile gradient-temperature hydrothermal method to synthesize hierarchical Zn2SnO4 hollow boxes based on phase transformation between metastable ZnSnO3 and stable Zn2SnO4. This strategy is widely extended to ZnSnO3 microspheres, ZnSn(OH)6 nanocubes and Co-ZIF-67 polyhedrons. When employed as a LIB anode, Zn2SnO4 hollow boxes exhibit apparently enhanced electrochemical performance.
