Resumo
The conversion of methane into methanol is one of the great challenges in the photocatalysis. In this
investigation WO3/TiO2 photocatalysts was synthesized by sodium borohydride (NaBH4) method. The
tungsten concentration was studied in the range of 5 to 20 atomic ratio. XRD results revealed a TiO2
anatase phase and WO3 peaks near the background noise. However, WO3 presence has been
highlighted by Raman spectroscopy, indicating the existence of both orthorhombic and amorphous
phase.The photocatalyst experiments showed that all materials enable the methanol production in
UVC irradiation, and only the materials with WO3 content produced the alcohol in white light
irradiation. The high conversion was observed for WO3(10)/TiO2(90) with 3.5 mmol h-1. The conversion of methane to methanol was most promising using WO3(10)/TiO2(90) due high conversion and no other
products observed in FTIR spectra.
