Nano-zirconia supported by graphitic carbon nitride for enhanced visible light photocatalytic activity.

Graphitic carbon nitride (g-CN) was prepared by high-temperature calcination of urea. A mixture of g-CN and nano-ZrO precursor was directly calcined to prepare g-CN/ZrO hybrid photocatalysts. The photocatalytic properties of the sample were characterized by degradation of rhodamine B (RhB) under visible light.
