Heterostructured Cu2O–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 Cu2O core and an Au shell. The C...

Description
Summary: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 Cu2O core and an Au shell. The Cu2O–Au 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. Moreover, this heterostructure realizes an integration of catalytic efficiency, retrievability, and versatility. In further consideration of the facile preparation process and low-cost material source of the structure, the Cu2O–Au NWs show a promising application prospect in the field of multifunctional photocatalysts.
