چکیده

در این پژوهش ابتدا نانوساختارهای پروسکایت La2CuO4 با استفاده از روش سونوشیمیایی تهیه شدند. روش مذکور جز روش‌هایی در شیمی می‌باشد که مورفولوژی یکدست را ایجاد می‌کند. این سنتز در شرایط نسبت مولی 2:1 از مس و لانتانیوم انجام شد و زمان 10 دقیقه و توان 45 وات باعث ایجاد مورفولوژی بهتر گردید. پس از سنتز نیمه‌هادی موردنظر با استفاده آنالیزهای شناسایی همانند الگوی پراش اشعه ایکس XRD، اشعه مادون‌قرمز FT-IR، سنجش مغناطیس نمونه ارتعاشی VSM، طیف‌سنجی بازتاب انعکاسی DRS، تئوری BET و میکروسکوپ الکترونی روبشی FE-SEM از تشکیل ساختار موردنظر اطمینان حاصل شد. بعد از اطمینان از تشکیل ساختار موردنظر تست-های فتوکاتالیستی آن گرفته شد که در پایان رنگزا اسید بلک با میزان ٪ 11/99 بیشترین میزان تخریب را داشته است.

Removal of chemical contamination using La2CuO4 photocatalyst with perovskite structure

چکیده [English]

In this study, first La2CuO4 perovskite nanostructures were prepared using sonochemical method. This method is one of the methods in chemistry that creates a uniform morphology. This synthesis was performed in a 2:1 molar ratio of copper and lanthanum and a time of 10 minutes and a power of 45 watts resulted in a better morphology. After synthesizing the desired semiconductor using detection analyzes such as XRD, FT-IR, VSM, DRS, BET theory and FE-SEM of the structure The comment was confirmed. After confirming the formation of the desired structure, photocatalytic tests were taken, which in the end, the dye Acid black1  had the highest amount of  99.11% degradation.
