Preparation of multi-dimensional (1D/2D/3D) carbon/g-CN composite photocatalyst with enhanced visible-light catalytic performance.

A multi-dimensional (1D/2D/3D) carbon/g-CN composite photocatalyst (CCN) was successfully prepared by a facile method with carbon from cheap absorbent cotton wool. The activities and stabilities of CCN were evaluated by photo-degrading Rhodamine B (RhB) under visible light irradiation. The effect of carbon content in composite on the catalytic activities was investigated.
