Synthesis of Cu2SnSe3-Au heteronanostructures with optoelectronic and photocatalytic properties.
Cu2SnSe3-Au heteronanostructures have been successfully synthesized for the first time using a seed-mediated growth method. Such new Cu2SnSe3-Au heteronanostructures demonstrate enhanced and broadened optical absorption in the Vis-NIR region. We have also investigated the optoelectronic and photocatalytic properties of the Cu2SnSe3-Au heteronanostructures and proposed a mechanism to illustrate the improved photocurrent and photocatalytic performance as compared to bare Cu2SnSe3.
