Heterostructured CuO-Au nanowire as a dual-functional nanocomposite for environmental pollutant degradation and hydrogen peroxide sensing.

Materials engineering is generally regarded as one of the most effective methods in the construction of photocatalysts, but it still faces many challenges. In this context, we designed and prepared a three-dimensional (3D) heterostructure of nanowires (NWs) formed by core and an Au shell. The - NWs not only show fine photocatalytic ability but also proved to have Fenton-like chemical properties and can be used as a hydrogen peroxide sensor.
