“…[ 1–6 ] A key advantage is that nanoparticles have manifold properties that differ significantly from those of bulk materials. Among others, examples such as the localized surface plasmon resonance of noble metal nanoparticles [ 7 ] or the size quantization effect in semiconductor nanoparticles [ 8,9 ] can be mentioned. Due to their high surface‐to‐volume ratios, nanoparticles are perfectly suited for processes that take place at the surface.…”

In this work, a new type of multicomponent nanostructures is introduced by forming interpenetrating networks of two different nanomaterials. In detail, gel networks from semiconductor nanorods are interpenetrated by Au nanowires. Two different types of gelling agents, namely S2− and Yb3+, are employed to trigger the network formation. The structural and electrochemical properties of the resulting materials are discussed. (Photo)electrochemical measurements are performed on the structures to compare the materials in terms of their conductivity as well as their efficiency in converting photonic energy to electrical energy. The new type of CdSe/CdS:Au nanostructure gelled with S2− shows one order of magnitude higher photocurrent than the system gelled with Yb3+. Moreover, the introduction of Au nanowires exhibit a photocurrent which is two orders of magnitudes higher than in samples without Au nanowires.
