Crystal phase-directed growth of rutile/anatase TiO2 heterojunctions via in situ stepwise chemical bath deposition below 80 °C
Abstract
The fabrication of hierarchical TiO2 phase junctions, such as rutile/anatase heterostructured films, via a low-temperature crystallization, has long been a challenge due to the lack of effective reaction strategies. In this study, we developed a temperature-gradient double-stage chemical bath deposition (CBD) method to produce rutile/anatase TiO2 thin films.
