Abstract

High specific surface area nanotube g-C₃N₄ was fabricated by a simple two-step condensation method. Photocatalytic activity was evaluated by decomposition of Rhodamine B (Rh B) under visible light. Nanotube g-C₃N₄ showed 12 times higher photocatalytic activity than bulk g-C₃N₄. The improvement of photocatalytic activity was mainly due to the higher surface area, the unique morphology and the number of defects.
