Template-directed Nanoengineering for Promoted Solar Water Splitting — •Min Zhou, Yang Xu, Liying Liang, Benrong Hai, and Yong Lei — Ilmenau University of Technology, Ilmenau 98693, Germany

Highly ordered nanostructures have attracted intensive attention in the field of solar water splitting due to their ordered nanoscale features, such as huge surface area, favorable transport properties and extended light absorption range from UV to visible light, etc. Template-directed fabrication is a facile and controllable approach to realize such nanoarchitectures. Having inherited the geometrical characteristics of the templates, the resulting water splitting cells demonstrate that the as-obtained nanoarchitectures benefit the photoelectrochemical reactions. For example, based on anodic aluminium oxide (AAO) templates, well-ordered CdTe/TiO2 core/shell nanowire arrays show promoted photocurrent response to visible light. Au particle array together with ferroelectric materials was realized by a cost-effective nonlithographic route, resulting in enhanced water splitting performance through surface plasmon resonance and controllable charge transfer/transport. Overall, template-directed nanoengineering shows excellent promising to make progress in solar energy-related applications.
