چکیده

هدف از انجام کار حاضر تهیه بستر مناسب برای لایه نشانی دی اکسید تیتانیوم به عنوان یک فوتوکاتالیست بر روی آلومینیوم است. به دلیل چسبندگی ضعیف فوتوکاتالیست ها بر روی آلومینیوم امکان لایه نشانی بر روی آن وجود ندارد و یا عمر بسیار کمی دارد. به همین دلیل در این مطالعه چسبندگی بین دی اکسید تیتانیوم (TiO2) و بستر آلومینیومی با ایجاد منافذ میکرونی بر روی سطح بستر با استفاده از دو روش آندایزینگ و اکسیداسیون الکترولیتی پلاسمایی (PEO) افزایش داده شده و نتایج دو روش مقایسه شده اند. آزمایش هایی نیز به منظور بررسی میزان حذف رنگینه با گذشت زمان با استفاده از محلول آبی رنگ رودامین 6G و در حضور تابش نور فرابنفش UV انجام شد. همچنین تصاویر SEM از سطح بستر های آلومینیوم لایه نشانی شده با TiO2 تهیه گردید. نتایج مطالعه نشان داد که تراکم منافذ روی سطح آلومینیوم در روش PEO بیشتر از روش آندایزینگ معمول بوده و در نتیجه حذف رنگینه در روش PEO بیشتر بوده است. علاوه بر این با این که حذف رنگینه در روش PEO نسبت به روش آندایزینگ افزایش یافته است، زمان کل فرآیند و انرژی مصرفی در این روش به خصوص در حالت پالسی کمتر از روش آندایزینگ است.

چکیده [English]

The purpose of the present work is to provide a suitable substrate for the deposition of titanium dioxide as a photocatalyst on aluminum. Due to the weak adhesion of photocatalysts to aluminum, there is no possibility of adhering photocatalysts to its surface or the lifetime is very short. For this reason, in this study, the adhesion between TiO2 and aluminum substrate is enhanced by the creation of micron pores on the substrate surface using two methods of anodizing and Plasma Electrolytic Oxidation (PEO) and the results of the two methods are compared. Experiments were carried out to investigate the dye removal over time using Rhodamine 6G aqueous solution in the presence of UV light. SEM images were also prepared from the surface of TiO2-coated aluminum substrates. The results of the study showed that the density of pores on the aluminum surface, and consequently, the dye removal in the PEO method were higher than those of conventional anodizing. In addition, although the dye removal in the PEO method is increased compared to the anodizing method, the overall process time and energy consumption in this method, especially in the pulse mode, were less than those of the anodizing method.
