Titanium oxide is commonly considered as an effective catalyst for photo-electrochemical water splitting due to its low cost, high activity, and perfect stability. However, a wide bandgap of TiO2 prevents the utilization of visible and near-infrared photons in the photo-electrochemical process. Photosensitization of TiO2 with plasmon active nanostructures was proposed as a way to solve this problem but the optimal design of coupled TiO2- plasmonic nanostructures, as well as the exact mechanism of plasmon triggering, are still under debate. In this work, we propose a plasmon-based TiO2 photosensitization, using the gold grating, covered by homogenous TiO2 layer.
