Abstract

A composite photocatalyst, Pd-TiO_2-xN_x-WO₃, was synthesized by the template method and characterized by energy dispersive X-ray microanalysis (EDX), X-ray diffraction (XRD), UV-vis spectrometer, and scanning electron microscope (SEM). The results of EDX analysis reveals that the molecular formula of the composite photocatalyst can be expressed as Pd-TiO_1.72N_0.28-WO₃. The UV-vis absorption spectrum indicates that the absorption edge of the catalyst red-shifts to around 600 nm. Under the irradiation with ultraviolet and visible light, the catalyst showed good performance for photocatalytic hydrogen production with a Na₂S/Na₂SO₃ system as the sacrificial agent.
