Abstract

Well-defined photocatalyst with 3D morphologies have attracted the attention of scientists due to the more accessiblereactive surfaces, easy to recover from reaction medium, and low aggregation. Within this scope, photocatalysisbased on plasmonic metal-organic frameworks (MOFs) were synthesized and utilized as an alternative reactive platformfor visible-light degradation of methylene blue (MB) under green LED irradiation for the first time. In order to reduce therecombination between electron-hole pairs, a stable oxidant, namely sodium persulfate (PS) was employed to acceleratethe photocatalytic decolorization of MB. These feasible strategies demonstrated that a bleaching degree of 91% (i.e., in thepresence of PS) within 120 min was achieved compared to the bare Au@UiO-66@Pdop NPs (bleaching degree 31%). Theobtained results from this study highlighted the superior properties of the newly synthesized core-shell Au@UiO-66@Pdopphotocatalysts and clearly declared the great potential of the photo-responsive MOFs for organic pollutant degradationsas well.

Özet

3 boyutlu morfolojiye sahip iyi tanımlanmış fotokatalizörler, daha erişilebilir reaktif yüzeyler, reaksiyon ortamından kolay bir şekilde elde edilebilmeleri ve düşük agregasyona sahip olmalarından dolayı bilim adamlarının dikkatini çekmiştir. Bu kapsamda, plazmonik metal organik çerçeve (MOF’ler) esaslı fotokatalizör sentezlendi ve ilk kez yeşil LED ışık ışınımı aracılığıyla metilen mavisinin (MB) görünür ışık altındaki degradasyonu için alternatif bir reaktif platform olarak kullanılmıştır. Elektron-boşluk çiftleri arasındaki rekombinasyonu azaltarak MB’nin fotokatalitik renksizleştirilmesini hızlandırmak için istikrarlı bir oksidan olan sodyum persülfat (PS) kullanılmıştır. Uygulanan stratejiler aracılığıyla çıplak Au@UiO-66@Pdop NP’lere kıyasla (yıkım derecesi %31) PS kullanılarak 120 dakika içinde %91’lik bir degredasyon derecesinin eldesi gösterilmiştir. Bu çalışmadan elde edilen sonuçlar, yeni sentezlenmiş çekirdek kabuk (core-shell) yapısındaki Au@UiO-66@Pdop fotokatalizörünün üstün özelliklerini vurgulamış ve ışık duyarlı MOF’lerin organik kirleticilerin degradasyonu için de mükemmel potansiyelini açık şekilde ortaya koymuştur.
