Porous V<inf>2</inf>O<inf>5</inf>/TiO<inf>2</inf>nanoheterostructure films with enhanced visible-light photocatalytic performance prepared by the sparking method

© 2020 by the authors. Porous V2O5/TiO2 nanoheterostructure films with different atomic ratios of Ti/V (4:1, 2:1, 1:1, and 1:2) were synthesized by a sparking method for the first time. The sparking method, which is a simple and cost-effective process, can synthesize highly porous and composite film...
