METHOD FOR MANUFACTURING OF COPPER AND NITROGEN-DOPED MESOPOROUS TITANIUM DIOXIDE HAVING LARGE SURFACE AND HIGH PHOTOCATALYTIC ACTIVITY IN VISIBLE RANGE

摘要

PURPOSE: A method for preparing a mesoporous titanium dioxide photocatalyst on which copper and nitrogen are doped is provided to obtain a titanium dioxide photocatalyst with excellent activity within a visible light. CONSTITUTION: A method for preparing a mesoporous titanium dioxide photocatalyst on which copper and nitrogen are doped comprises: a step of mixing and stirring titanium isopropoxide, a nitrogen precursor, distilled water, and ethanol and preparing a first mixture solution; a step of boiling the first mixture solution in a water bath and drying to prepare a titanium dioxide photocatalyst on which copper and nitrogen are doped; a step of mixing the nitrogen-doped mesoporous titanium dioxide, a copper oxide precursor, distilled water, and ethanol and preparing a second mixture solution; and a step of stirring and drying the second mixture solution.
