TiO2 and Fe2O3 Films for Photoelectrochemical Water Splitting

Popis výsledku v původním jazyce

Titanium oxide (TiO2) and iron oxide (alpha-Fe2O3) hematite films have potential applications as photoanodes in electrochemical water splitting. In the present work TiO2 and a-Fe2O3 thin films were prepared by two methods, e.g., sol-gel and High Power Impulse Magnetron Sputtering (HiPIMS) and judged on the basis of physical properties such as crystalline structure and surface topography and functional properties such as simulated photoelectrochemical (PEC) water splitting conditions. It was revealed that the HiPIMS method already provides crystalline structures of anatase TiO2 and hematite Fe2O3 during the deposition, whereas to finalize the sol-gel route the as-deposited films must always be annealed to obtain the crystalline phase. Regarding the PECactivity, both TiO2 films show similar photocurrent density, but only when illuminated by UV light. A different situation was observed for hematite films where plasmatic films showed a tenfold enhancement of the stable photocurrent densit
