Abstract

In this work, we report for the first time a unique configuration of N-doped and Cu-doped TiO₂ bilayer. The activity of TiO₂ was improved by combining Cu- and N-doping in a layered thin-film structure. The impact of the stacking order was studied, pointing out how the best arrangement is by far the one with Cu-TiO₂ as the top layer. The results reveal a unique and simple way to enhance the photocatalytic response of TiO₂ in the visible domain.
