A functional Ag-TiO nanocomposite solar selective absorber with antimicrobial activity by photochemical reduction process.

A functional nanocomposite coating developed by wet chemical route in a photochemical reduction process will be a good candidate for low temperature solar thermal application. The low-temperature curable cermet comprises of two different type of nanoparticles, generated by photocatalytic reduction of silver ions under the sunlight with the aid of crystalline TiO (~8 nm) nanoparticles. The optimized base absorber layer of Ag-TiO nanocomposite exhibited absorptance (α) of 0.
