摘要：

A tungsten trioxide (WO3) nano-film was prepared by a sol-gel method using tungsten powder and hydrogen peroxide as the starting materials. Then, platinum was doped onto the WO3 film surface by a magnetron sputtering method. A tunnel-atomic power microscope was used to characterize the WO3. We theoretically analyzed the WO3 film's hydrogen-sensitive mechanism as well as conducted research into the film's optical properties. The results indicate that the WO3 nano-film mixed with Pt possesses a good hydrogen sensitivity and restorative quality.
