Multilayer graphene in the interplay with different photocatalyst architectures for the hydrogen evolution reaction

Universität Rostock, 2016

Abstract: The use of graphene as co-component for nanostructured materials has led to the claim of improving efficiencies of solar cells, fuel cells and particular in photocatalytic systems for solar water splitting. As a result of exceptional conductivity properties it is believed that graphene might always enhance the separation of charge carriers, consequently increasing photocatalytic performances. However, herein is demonstrated that employing graphene in different configurations, i.e. powder suspension, multicomponent aerogel and electrode, the photocatalytic enhancement is rather case sensitive.
