Abstract
The invention provides a preparation method for a photocatalyst with broadband spectrum response. The photocatalyst with broadband spectrum response is a nitrogen iron-doped bismuth tungstate compound titanium dioxide nano-particle or nano-tube. The preparation method for the photocatalyst with broadband spectrum response comprises the following steps: preparing a titanium dioxide nanometer material; doping nitrogen and iron into the titanium dioxide nanometer material; and preparing the nitrogen iron-doped bismuth tungstate compound titanium dioxide nanometer material. The invention combines ion doping modifying and semiconductor compound modifying techniques for expanding the ultraviolet part of the photocatalyst with broadband spectrum response scope below 387nm to a near-infrared band, the visible light and near-infrared light response of the nanometer titanium dioxide photocatalyst is realized and the catalytic activity of the nanometer carbon dioxide photocatalyst is enhanced.
