The anatase TNPs exhibit high fractions of {001} facets, which have high photocatalytic activity. The TNRs are obtained in a brookite/anatase mixture. Some studies suggest that brookite shows superior photocatalytic activity in certain applications. We also varied the TNC concentration within the hybrid films, (Supporting Information, Section S6) resulting in i) increased rates of reduction and ii) higher overall conductances for higher TNC concentrations. Comparative reference experiments in which pure GO films were exposed to DUV light confirmed the enhancement and acceleration of rGO formation in the presence of a TNC photocatalyst (Supporting Information, Section S7). Generally, our findings demonstrate that the conductance of (GO/rGO)/TNC hybrid films can be enhanced and tuned over several orders of magnitude by DUV illumination and by variation of the TNC catalyst as well as the film thickness.
