Abstract

A preparation method of inverse opal material for visible-light-driven photocatalytic degradation of organic pollutants includes 1) using titanium dioxide precursor as raw material, preparing nitrogen-doped titanium dioxide inverse opal by one-step process in the presence of nitrogen source, and 2) in the presence of reducing agent, using the nitrogen-doped titanium dioxide inverse opal, selenium precursor, and cadmium precursor as raw materials to prepare the cadmium selenide sensitized nitrogen-doped titanium dioxide inverse opal.
