In this study, ZnO loaded on cotton stalk activated carbon (ZnO/CSAC) has been successfully synthesized by the chemical precipitation method. XRD patterns showed that ZnO/CSAC have two phases are hexagonal wurtizite and amorphous structures. The average particle size is reduced (12.4 nm) upon loading CSAC than the ZnO NPs. The band gap value is decreased (2.50 eV) upon loading on CSAC compared to ZnO NPs. The functional groups identify using by FT-IR spectrum. FE-SEM images a pure ZnO revealed a 15–40 nm spherical structure and 10–35 nm large agglomerations spherical structure for ZnO/CSAC and then, EDAX spectrum affirmed the formation of ZnO/CSAC. BET surface area and pore volume of the 22.18 m 2 g −1 and 0.210 cm 3 g −1 for the ZnO NPs and make it increased surface area and pore volume due to the adding CSAC to 263.18 m 2 g −1 and 0.306 cm 3 g −1 . The photocatalytic degradation efficiency of brilli...

亮绿色染料对棉秆活性炭负载ZnO的光催化效率

在这项研究中，已通过化学沉淀法成功合成了负载在棉秆活性炭上的ZnO（ZnO / CSAC）。XRD图谱表明，ZnO / CSAC具有六角六方锰锌矿和非晶结构两相。装载CSAC时，平均粒径比ZnO NPs减小（12.4 nm）。与ZnO NPs相比，CSAC加载后，带隙值降低（2.50 eV）。官能团通过FT-IR光谱识别。FE-SEM图像显示纯ZnO揭示了ZnO / CSAC的15–40 nm球形结构和10–35 nm的大团聚球形结构，然后EDAX光谱确认了ZnO / CSAC的形成。ZnO NP的BET表面积和孔体积为22.18 m 2 g -1和0.210 cm 3 g -1，并且由于在263.18 m 2 g -1和0中添加CSAC而使其表面积和孔体积增加。306 cm 3 g -1。溴化物的光催化降解效率
