A novel structure of nitrogen doped carbon (NC) modified three-dimensional ordered macroporous titanium dioxide (NC/3DOM-TiO2) was constructed by using dopamine hydrochloride as the carbon/nitrogen source.By adjusting the concentration of this organic precursor,the thickness of NC layers could be well loaded and controlled.Compared with pure 3DOM-TiO2,the photocatalytic activities of NC/3DOM-TiO2 were much higher under visible-light irradiation.Based on the characterization results,a possible mechanism of enhanced photocatalysis was proposed.
