Abstract

Appropriate wastewater treatment methods for effectual and practical decontamination of wastewater bodies is the prime goal of today’s environmentalists and industrialists. Herein, sunlight driven photocatalytic degradation of rhodamine-B (RhB) has been investigated by employing hydrothermally synthesized tin oxide-graphene oxide (SnO2/GO) nanocomposite. Physiochemical characterization of composite has been accomplished via X-ray diffraction (XRD) analysis, ultraviolet (UV) spectroscopy, diffused reflectance spectroscopy (DRS) and photoluminescence (PL). Photocatalytic degradation of RhB is studied using UV light and spectrophotometer. SnO2-GO nanocomposite degraded the RhB dye in 120 min comparatively in quite lesser time than separate SnO2 and GO degradation performances. The incorporation of GO into SnO2 decreases the rate of electron–hole recombination, increases the oxidation of carriers as well as the rate of carrier separation owing to the synergistic impact of GO and SnO2. Therefore, an affordable graphene oxide supported SnO2 nanocomposite can be implicated as efficacious real wastewater treatment method at industrial scale.

氧化锡-氧化石墨烯（SnO2/GO）纳米复合材料：一种有前途的降解罗丹明-B染料的光催化剂

适当的废水处理方法对废水体进行有效和实际的净化是当今环保主义者和工业家的首要目标。本文采用水热合成的氧化锡-氧化石墨烯(SnO2/GO)纳米复合材料，研究了阳光驱动的光催化降解罗丹明- b (RhB)。通过x射线衍射(XRD)分析、紫外(UV)光谱、漫反射光谱(DRS)和光致发光(PL)对复合材料进行了理化表征。采用紫外光和分光光度计研究了RhB的光催化降解。SnO2-GO纳米复合材料降解RhB染料的时间为120 min，比单独降解SnO2和GO的时间短得多。由于氧化石墨烯与SnO2的协同作用，氧化石墨烯掺入SnO2降低了电子-空穴复合的速率，增加了载流子的氧化和载流子的分离速率。因此，一种经济实惠的氧化石墨烯负载的SnO2纳米复合材料可以作为工业规模上有效的真正的废水处理方法。
