Green sacrificial template fabrication of hierarchical MoO3 nanostructures

Abstract

This work focuses on the construction of three-dimensional (3D) hierarchical MoO₃ nanostructures using a wet chemistry method of sacrificing VO₂ nanoarray templates. Results suggest that the whole process involves the templates' gradual dissolution and the corresponding hierarchical MoO₃ nanorods' oriented growth. This strategy of fabricating hierarchical nanostructures through in situ conversion is potentially scalable and could be applicable for controllable syntheses of other related hierarchical nanostructures.
