Abstract: | Hierarchical Cu2O/Au/CuO nanostructures have been achieved by water-based green fabrication at a low temperature. Precluding the requirement of the template removal, the generation of hierarchical architecture relied on the catalytic activity of gold nanoparticles attached on the Cu2O nanocubes. Notably, we creatively developed the dual-roles catalytic ability of gold, which not only remarkably increased the specific surface area of this architecture, but also provided the enhanced performance for gas sensing. |
