Nitrogen doped carbon aerogel composites with TiO2 and ZnO prepared by atomic layer deposition†
A nitrogen doped carbon aerogel was used as a substrate for the atomic layer deposition of TiO2 and ZnO layers in various thicknesses. The bare and composite products were analyzed using Raman spectroscopy, XRD, N2 adsorption, SEM-EDX, TEM, XPS, and ICP-OES and their photocatalytic activity was investigated in decomposing methyl orange dye under UV light irradiation. We investigated the effect of the different metal oxides and their thickness dependence on the photocatalytic activity.
