Abstract

Contaminants are repeatedly being released into the land, water and air about the world as a consequence of the high levels of human movement and development, which causes a fast an increase in the growing of pollution. In this assessment, activated charcoals supported on Ag-InO nanomaterials were blended by hydrothermal system. The morphology constitution, surface assets and optical description of synthesized nanomaterials were characterized by XRD, UV-DRS, PL, HR-SEM and EDAX, HR-TEM, SAED pattern, FT-IR, XPS, BET, CV and VSM techniques. The optimized heterogeneous catalyst AC/Ag-InO depicts high electro catalytic activity, fast-charge transport development, weak ferromagnetism, brilliant accessibility and stability for Rh6G dye degradation, which is endowed for application in the alkaline medium. The prepared photocatalytic activity towards AC/Ag-InO have been revealed as the degradation of Rhodamine 6G (Rh6G) dye in the presence of aqueous solution directed to solar light irradiation. AC/Ag-InO is initiated to maintain some more efficient than synthesized Ag-InO and InO by positively mineralizing of Rh6G dye under sun light irradiation. The mineralization of Rh6G dye has been confirmed by measuring COD analysis. It is suggested that Rh6G degrades in the presence of solar light via a particular mechanism, which was discovered that the catalyst remained more stable and reusable. It has been effectively determined that the AC/Ag-InO nanomaterial achieves photocatalytic effects.

摘要

由于人类高度的活动和发展,污染物不断地被释放到世界各地的土地、水和空气中,这导致污染快速增加。在本评估中,通过水热系统将负载在Ag-InO纳米材料上的活性炭进行混合。通过XRD、UV-DRS、PL、HR-SEM和EDAX、HR-TEM、SAED图谱、FT-IR、XPS、BET、CV和VSM技术对合成纳米材料的形态结构、表面性质和光学特性进行了表征。优化后的非均相催化剂AC/Ag-InO对罗丹明6G(Rh6G)染料降解表现出高电催化活性、快速电荷传输性能、弱铁磁性、良好的可及性和稳定性,适用于碱性介质。所制备的AC/Ag-InO的光催化活性表现为在水溶液中,以太阳光照射下对罗丹明6G(Rh6G)染料的降解。通过对Rh6G染料进行正矿化,AC/Ag-InO在太阳光照射下比合成的Ag-InO和InO更高效。通过测量COD分析证实了Rh6G染料的矿化。结果表明,Rh6G在太阳光存在下通过特定机制降解,发现该催化剂更稳定且可重复使用。已有效确定AC/Ag-InO纳米材料具有光催化效果。
