Cover Story: Titania-based photocatalysts have been intensively studied for various applications during the last fifty years, including environmental purification, solar energy conversion and organic synthesis. Despite broad scientific interest and even commercial use, two shortcomings (charge-carriers’ recombination and UV-limited photoabsorption) should be overcome for successful commercialization of titania, and thus, various strategies have been proposed. Can defective (self-doped) titania be considered as UV/vis/NIR active photocatalysts? Is the type of defect important (charge carriers’ recombination center)? Does black titania mean an efficient photocatalytic material? This paper is an attempt to answer those crucial questions, based on the characterization and photocatalytic activity data for different (mainly black) titania samples. View this paper
