Abstract

Single-crystalline Mn₃O₄ nanowires were prepared using the vapor-phase transformation of ZnO nanobelts. Mn₃O ₄-decorated ZnO nanobelts and ZnO-ZnMn₂O₄ core-shell nanocables (NCs) were also obtained as reaction intermediates. Heteroepitaxial growth of tetragonal spinel Mn₃O₄ (or ZnMn₂O₄) on wurtzite ZnO is a possible reason for the growth of single-crystalline Mn₃O₄ nanowires. Growth interfaces are possibly formed between the wurtzite (101̄0)/ (21̄1̄0) and spinel (1̄01)/(4̄11) planes. Various one-dimensional homonanostructures and heteronanostructures consisting of n-ZnO, p-Mn₃O₄, and p-ZnMn₂O₄ can be used to design high-performance gas sensors.
