Abstract
This invention discloses a method for fabricating a gold/titanium dioxide core-shell structured photocatalyst and the application thereof to photocatalytic decomposition of organic compounds under ultraviolet irradiation. The method comprises steps: fabricating a solution of gold ions; fabricating gold/titanium dioxide core-shell structured nanoparticles; and crystallizing the gold/titanium dioxide core-shell structured nanoparticles, wherein gold and titanium dioxide are mixed by a weight ratio of 0.005 to 0.03. The gold/titanium dioxide core-shell structured photocatalyst can effectively decompose organic compounds and dyes under ultraviolet irradiation.
