Formation of Self-Assembled Defect-Free Zn₂SnO₄ Nanostructures from Binary Oxides without the Kirkendall Effect

Abstract

In this Communication, we report a facile approach to synthesize a technologically important oxide Zn2SnO4 (ZTO) by a temperature-dependent solid-state reaction without the Kirkendall effect. Single-phase defect-free ZTO was formed upon calcination of a homogeneous 2:1 mixture of reactive ZnO rods and SnO2 nanoparticles at 1000 °C. We also observed interesting photocatalytic and photovoltaic properties from the synthesized ZTO material.
