Abstract Reduced graphene oxide (RGO)-TiO2 nanotubes (TNTs) were used for industrial wastewater treatment that was obtained from Banwol Sihwa Industrial Complex, Korea. RGO-TNT were fabricated using one-step and two-step anodization at different RGO concentrations, RGO deposition times, anodization voltages and anodization times. Synthesized catalysts were characterised using FESEM, XRD, TEM, EDS, XPS, UV–vis DRS, PL, Raman, and pHPZC. Compared with pure-TNTs, two-step and one-step RGO-TNT exhibited 2.7 and 3.3-times higher photocatalytic activities for industrial wastewater. Scavenger experiments identified that OH and e− are main species involved in photocatalytic degradation of MB and industrial wastewater. RGO-TNTs are suitable for industrial wastewater treatment.

合成参数对工业废水处理用石墨烯-TiO 2 纳米复合材料可见光光催化活性的影响

摘要 还原氧化石墨烯 (RGO)-TiO2 纳米管 (TNTs) 用于工业废水处理，从韩国 Banwol Sihwa 工业园区获得。RGO-TNT 使用一步和两步阳极氧化在不同的 RGO 浓度、RGO 沉积时间、阳极氧化电压和阳极氧化时间制造。合成的催化剂使用 FESEM、XRD、TEM、EDS、XPS、UV-vis DRS、PL、拉曼和 pHPZC 进行表征。与纯 TNT 相比，两步和一步 RGO-TNT 对工业废水的光催化活性分别高出 2.7 和 3.3 倍。清除剂实验确定 OH 和 e- 是参与 MB 和工业废水光催化降解的主要物质。RGO-TNTs 适用于工业废水处理。
