Abstract

Solvent-mediated particle aggregation was employed to produce nanoparticle networks containing a high abundance of functional interfaces. Using electron paramagnetic resonance spectroscopy (EPR), we experimentally observed that the intentional attachment of vapor-grown ZrO$_2$ nanocrystals to TiO$_2$ particle surfaces yields networks of intermixed nanoparticles with substantially improved charge separation properties. The superior performance holds also in comparison to homogeneous ZrO$_2$ and TiO$_2$ nanoparticle networks that exhibit a higher charge recombination loss in comparison to powders of unconnected nanocrystals.
