Composite having high photocatalytic activity in visible range and preparation method thereof

摘要

The present invention relates to a composite having high visible light activity and a method for producing the composite. Specifically, the composite is formed by reducing titanium dioxide nanorods formed on a substrate through electrochemical reduction to have a low band gap, And the seed layer is introduced by a RF magnetron sputtering method during the production of the composite to prevent the titanium dioxide nanorod from being damaged or peeled off from the substrate during the electrolytic reduction method to improve the durability, Further, there is an effect that the optical activity is further improved by depositing a platinum (Pt) thin film on the surface of the reduced titanium dioxide nanorod.
