Utilization of waste beverages for achieving carbon-based core-shell nanostructures of high visible light photocatalytic performance.

Waste beverages are utilized as resources in various valuable, albeit energy-consuming, waste-to-energy processes. There is a growing need for alternative cost-effective methods to harness their potential. This study explored the feasibility of employing waste beverages as feedstock for the counterpart component of a TiO-based composite photocatalyst.
