Abstract

Photo-activated processes have been widely recognized as cost-effective and environmentally friendly routes for both renewable energy generation and purification/cleaning technologies. We report herein on a plasma-assisted approach for the synthesis of Fe2O3-TiO2 nanosystems functionalized with Au n...
