InVO<inf>4</inf>–BiVO<inf>4</inf>composite films with enhanced visible light performance for photodegradation of methylene blue
© 2016 Elsevier B.V. The InVO4, BiVO4, and InVO4–BiVO4films were fabricated by a simple doctor blading coating technique. The film thickness of the as-prepared samples was varied to one, two and three layers. The prepared InVO4–BiVO4composite films were characterized in detail by various analytical...
