Hidrobenzoin Sübstitüe ZnPc/SBA-15 Heterojen Fotokatalizörü ile Metilen Mavisi Gideriminin İncelenmesi

Öz

Bu çalışmada, sulu ortamlardan organik bir kirletici olan metilen mavisinin (MB) etkin bir şekilde uzaklaştırılması için sürdürülebilir bir fotokatalizörün uygulanması sunulmuştur. Gözenekli bir malzeme olan SBA-15 üzerine desteklenmiş, güçlü ışık soğurma yeteneğine sahip klorofil benzeri bir bileşik olan çinko ftalosiyanin (ZnPc) içeren heterojen bir fotokatalizörün fotokatalitik aktivite testleri, 50 W kırmızı LED ışık kaynağı kullanılan özel bir 3D yazdırılmış reaktör sistemi ile laboratuvar ortamında gerçekleştirilmiştir. Deneysel sonuçlar, ZnPc-SBA-15’in yalnızca 90 dakikada 25 ppm MB’nin %92’sini uzaklaştırdığını ortaya koymuştur. Ayrıca yeniden kullanılabilirlik deneyleri, katalizörün üç ardışık kullanım sonrasında aktifliğini koruduğunu göstermiştir. Bu bulgular, ZnPc-SBA-15 fotokatalizörünün, düşük enerjili LED ışığı altında MB’nin bozunumu için çevre dostu ve ekonomik bir çözüm sunduğunu göstermektedir.

Investigation of Methylene Blue Removal by Hydrobenzoin-Substituted ZnPc/SBA-15 Heterogeneous Photocatalyst

Öz

In this study, the application of a sustainable photocatalyst for the efficient removal of methylene blue (MM), an organic pollutant, from aqueous environments is presented. Photocatalytic activity tests of a heterogeneous photocatalyst, consisting of zinc phthalocyanine (ZnPc), a chlorophyll-like compound with strong light absorption ability, supported on the SBA-15, a porous material, were conducted in a laboratory environment using a custom 3D-printed reactor system with a 50 W red LED light source. Experimental results revealed that ZnPc-SBA-15 removed 92% of 25 ppm MM in just 90 minutes. Furthermore, reusability experiments demonstrated that the same catalyst maintained its activity after three consecutive uses. These findings indicate that the ZnPc-SBA-15 photocatalyst offers both an environmentally friendly and economical solution for the degradation of MB under low-energy LED light.
