摘要：
As a key photocatalyst, Titanium oxide is commonly used, which has the advantages of non-toxic and good stability. However, due to its high photogenerated electron hole recombination rate, too wide band gap and other factors, its effective application in photocatalytic degradation is limited. Therefore, this work proposes a method of fabricating gold nanoparticles on the surface of titanium oxide film by using pulsed laser. Using the plasmon effect of gold nanoparticles, it is expected to obtain an efficient composite photocatalytic film. The results showed that under the effect of pulsed laser with a power of 5 x 10(7) W cm(-1), the gold nanoparticles were fabricated and evenly distributed. The composite film formed an obvious plasmon absorption peak near 550 nm, due to the effect of gold nanoparticles.
