Molecule‐Based Chemical Vapor Growth of Aligned SnO₂ Nanowires and Branched SnO₂/V₂O₅ Heterostructures

Abstract

Aligned SnO2 nanowire arrays and individual 1D structures were grown by a combination of molecule-based CVD and catalyst-assisted growth techniques on TiO2 substrates. Hierarchical branched SnO2/V2O5 heterostructures (see image) were obtained by a two-step process without secondary catalyst deposition leading to a red shift in the photoconductance of the SnO2/V2O5 structures compared to the pure SnO2 NWs.
