Gold-catalytic green synthesis of Cu_2O/Au/CuO hierarchical nanostructure and application for CO gas sensor
|
摘要
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.
