Graphene-based quantum dots as promoters of the photocatalytic activity of anodic nanostructured TiO2 nanotube layer

A poster was presented at the E-MRS 2023 Fall meeting in Warsaw on the 19th of September. General overview of the work : To improve the photocatalytic activity of TiO₂, a stable and available catalyst, the optical absorption edge can be moved to longer wavelengths, or improve photoinduced charge carrier separation. Introducing additional materials to TiO₂ can do both. Notably, the added material should be accessible and abundant; carbon nanomaterials seemed to be good candidates for the task. In this work carbon based nanoparticles (CNP) have been introduced into the TiO2 nanotube layer and changes in structural and photocatalytic activity are investigate
