The sol-gel technique was used to fabricate ZnO Nano-swirlings (ZNsw) at a predetermined agitation rate (of >> 1900 rpm), with around 21.94 gm of zinc acetate dihydrate and 0.2 g cetyltrimethylammoniumbromide (CTAB) and a cationic surfactant (drop-wise). The impact of the predetermined agitation condition on the molecular size and morphology of ZNsw is examined, and the outcomes are dissected by useful characterization tools and techniques viz. XRD, SEM embedded with EDS, TEM, FT-IR and UV-visible. The SEM and TEM results suggest that the product formed into a big cluster of adequate ZNsw, containing a significant quantity of folded long thread-lengths. Each group indicated a fair amount of the volume of these lengths. The photocatalytic process of ZNsw was carried out as a result of the irradiation time due to the deterioration of Azo Dye AR183, resulting in approximately 79 percent dye discoloration following an 80-min UV light irradiation in the presence of ZNsw. Additionally, the synthesized ZNsw was tested for antagonistic activity, and the growth hindrance of two plant pathogenic fungal strains found. Per cent inhibition in growth of Rhizoctonia solani and Alternaria alternata were observed in response to ZNsw.
采用溶胶-凝胶技术,在预定的搅拌速率(>>1900 rpm)下制备 ZnO 纳米漩涡(ZNsw),使用约 21.94 克三水合醋酸锌和 0.2 克十六烷基三甲基溴化铵(CTAB)和阳离子表面活性剂(逐滴加入)。研究了预定搅拌条件对 ZNsw 分子尺寸和形态的影响,并通过有用的表征工具和技术(如 XRD、SEM 嵌入 EDS、TEM、FT-IR 和 UV-可见)对结果进行了分析。SEM 和 TEM 结果表明,产物形成了大量的适当 ZNsw 大簇,其中包含大量折叠的长线程长度。每组都表明这些长度的体积相当大。ZNsw 的光催化过程是由于 Azo Dye AR183 的降解,在存在 ZNsw 的情况下,经过 80 分钟的紫外线照射,导致大约 79%的染料褪色。此外,还测试了合成的 ZNsw 的拮抗活性,并发现两种植物病原真菌菌株的生长受到抑制。ZNsw 对 Rhizoctonia solani 和 Alternaria alternata 的生长抑制率分别为 79%和 79%。
