چکیده

کاتالیزورهای نوری با استفاده از انرژی خورشید می‌توانند رنگزاهای آلی را تخریب کنند. امروزه علاقه به پژوهش در زمینه واکنش‌های کاتالیزوری نوری آب رو به افزایش است. در تحقیق حاضر چندین روش برای سنتز اکسیدهای مختلط باریم- منگنز بررسی شد. نانوکامپوزیت‌های BaMnO3 (Ba-Mn-O) با روش سنتز سل-ژل، با آزمون‌های مشخصه‌یابی مختلف شناسایی و به عنوان کاتالیزور نوری برای حذف آلودگی‌های رنگی آب استفاده شدند. بازده تخریب رنگزاهای آلی متیل اورانژ (MO)، آریوم کروم بلک تی (EBT)، رودآمین بی (RhB) و مالاکیت گرین (MG) در حضور کاتالیزورهای نوری سنتز شده مطالعه و شرایط بهینه برای بالا بردن میزان تخریب رنگزاها (شامل مقدار رنگزا و مقدار کاتالیزور نوری) بررسی شدند. بازده تخریب 88 درصد از MO و 69 درصد از EBT بعد از 90 دقیقه تابش مرئی در حضور این کاتالیزورهای نوری گزارش شدند. مقادیر ppm 10 رنگزا MO و 03/0 گرم فوتوکاتالیست به‌عنوان شرایط بهینه برای به دست آمدن بالاترین تخریب رنگزا (88 درصد) گزارش شد.

چکیده [English]

Photocatalysts can degrade organic dyes using solar energy. Nowadays, there is increasing interest in studying photocatalytic reactions in water. In this study, several methods for synthesizing Ba-Mn mixed oxides were investigated. BaMnO3 nanocomposites (Ba-Mn-O NCs) were created through the sol-gel process, characterized with various techniques, and used as photocatalysts to remove colored water pollutants. The effectiveness of these photocatalysts in degrading organic dyes such as methyl orange (MO), eriochrome black T (EBT), rhodamine B (RhB), and malachite green ((MG) was studied in the presence of the synthesized photocatalysts, and optimal conditions for improving dye degradation (including dye concentration and photocatalyst dosage) were examined. The results showed 88 % degradation of MO and 69 % degradation of EBT after 90 minutes of visible light exposure in the presence of the photocatalysts. The best conditions for maximum degradation (88 % for MO) were found to be 10 ppm of MO dye and 0.03 g of photocatalyst.
