Metal-semiconductor nanocomposites have been utilized in a multitude of applications in a wide array of fields, prompting substantial interest from different scientific sectors. Of particular interest are semiconductors paired with plasmonic metals due to the unique optical properties that arise from the individual interactions of these materials with light and the intercomponent movement of charge carriers in their heterostructure. This review focuses on the pairing of CuO semiconductor with strongly plasmonic metals, particularly Au and Ag.

- TiO-based nanomaterials are promising photocatalysts for degrading organic dye pollutants, and this study focuses on Au-TiO nanofibers created using electrospinning and heated at 500 °C.
- The composite structure features TiO nanofibers with Au nanoparticles embedded throughout, which enhances the photocatalytic performance when tested against dyes like Rhodamine B and methylene blue.
- The improved degradation efficiency of the Au-TiO nanofibers is attributed to the plasmon resonance of the Au nanoparticles and effective charge separation at the nanofiber junctions, highlighting their potential for cleaning dye contaminants from water using solar light.
