Fabrication of CuO-ZnO nanowires on a stainless steel mesh for highly efficient photocatalytic applications.

We report the photocatalytic activity of flower-like CuO-ZnO heterostructured nanowires (NWs) fabricated on a stainless steel mesh. The mesh provided an extensive surface area and facilitated efficient mass transfer. The composed NWs exhibited excellent photocatalytic activity and showed additional enhanced properties due to multilayered, dual light source effects during the photodecomposition of a non-biodegradable azo dye.
