| 英文摘要 | A novel graphene-bridged SrTiO3 (STO) thin film loaded on the glass was fabricated using a facile sol-gel method followed by the dip-coating and spin-coating method. As-prepared STO film and GO/STO film were tested by XRD, SEM to identify the composition and surface morphology. The as-prepared thin film catalyst was employed to degrade methylene blue (MB) in water under near ultraviolet ray irradiation. Compared to pure STO, GO/STO prepared by dip-coating method displayed good photocatalytic degradation efficiency with 58% removal of MB (60 mL, 5mg/L) in 6.0 h, the GO/STO prepared by spin-coating method displayed more superior degradation efficiency with 94% removal of MB (60 mL,5mg/L) in 6.0 h. The influences of MB volume and the different methods were also investigated in details. The enhanced photocatalytic activities could be attributed to the suppression of charge recombination, high specific surface area and great adsorption capability of GO/STO. This work provides a promising approach to construct novel film GO/STO with high stability and photodegradation efficiency that can be applied in efficient treatment pollutants in wastewater. 漏 2019 Trans Tech Publications Ltd, Switzerland. |
