Our main interest lays on on design, fabricate, and manipulate nanostructured materials focusing particularly on TiO2-based nanostructures (e.g., pure, doped, co-doped). By tuning the morphology and composition of nanoparticles and nanoparticle films, we aim to control the mobility of the charge carriers to develop high-performing devices for environmental and energy applications such as water splitting and gas sensing.
