Fabrication of Graphene-Based TiO₂@CeO₂ and CeO₂@TiO₂ Core-Shell Heterostructures for Enhanced Photocatalytic Activity and Cytotoxicity.

ABSTRACT: Development of light-harvesting properties and inhibition of photogenerated charge carrier recombination are of paramount significance in the photocatalytic process. In the present work, we described the synthesis of core-shell heterostructures, which are composed of titanium oxide (TiO₂) and cerium oxide (CeO₂) deposited on a reduced graphene oxide (rGO) surface as a conductive substrate. Following the synthesis of ternary rGO-CeO₂@TiO₂ and rGO-TiO₂@CeO₂ nanostructures, their photocatalytic activity was investigated toward the degradation of rhodamine B dye as an organic pollutant under UV light irradiation. The obtained structures were characterized with high-resolution transmission electron microscopy, field-emission scan
