The Front Cover shows the use of electron microscopy and spectroscopy to study the plasmonic enhancement in the photoelectrochemical activity of faceted rutile TiO 2 photoanodes using silver nanoparticles. In their Full Paper, Prof. Thomas Maschmeyer and co‐workers used directing agents to promote the creation of active grain boundaries in rutile TiO 2 thin films and optimise the further interaction with silver nanoparticles. Scanning electron microscopy using an Electron Backscatter Diffraction (EBSD) detector was used and the results were correlated with electrochemical impedance spectroscopy to reveal the optimised plasmonic interaction of silver on grain boundaries. An increase in the photoelectrochemical activity in the visible light‐stimulated photoelectrochemical activity was found.
