概要 Pt co-catalyst WO_3 (WO_3/Pt) nanoparticle has been synthesized with a variation of platinum co-catalyst mass percentage using the microwave-assisted sol-gel method. The XRD characterization results s...how that WO_3/Pt has a triclinic (anorthic) crystal structure. The touch diagram from UV-Vis DRS measurement exhibits that the energy band gap value of pristine WO_3 nanoparticle of 2.89 eV, while for WO_3/Pt was in the range of 3.23 – 3.43 eV. PL spectra depicted the photoluminescence intensity decreasing by the addition of Pt. WO_3/Pt improved photocatalytic properties in the degradation of methylene blue (MB) under visible light for 30 min irradiation up to 98.7% degraded.続きを見る
