Effect of Ag NPs on the radiant absorption of photocatalyst film

Blog Article

A composite film composed of Ag nanoparticles, Al2O3 and TiO2 was prepared by cosputtering.Ag NPs were immersed Diabetes Care in the Al2O3 host, TiO2 was deposited onto the Ag/Al2O3 layer.The degradation of aqueous methylene blue under incident irradiation indicated that the Ag/Al2O3-TiO2 composite film with the Ag-TiO2 distance of 2nm Bronzers or 5nm exhibited high degradation rate.Spectral absorptivity and radiant absorption distribution were analyzed through FDTD simulation to analyze the relationship between radiant absorption and photocatalytic activity.Results indicated that the spectrum and distribution of the radiant absorption in the composite film could be rationally regulated to improve photocatalytic activity.
