CuxZn(1-x)O Nanoparçacıklarıyla Dekore Edilmiş Kaolin Nanokompozitinin Sentezi, Karakterizasyonu ve Fotokatalitik Aktivitesi

Öz:
Kaolin yüzeyine CuxZn(1-x)O nanoparçacıkları dekore edilerek kaolin-CuxZn(1-x)O nanokompoziti hazırlandı. Saf kaolinin, saf CuxZn(1-x)O nanoparçacıkları ve hazırlanan bu kaolin-CuxZn(1-x)O nanokompozitin fotokatalitik aktiviteleri UVA ışınları altında Rodamin B boyar maddesinin fotokatalitik bozunması incelenerek değerlendirildi. Bütün numuneler SEM-EDX, XRD, FTIR, ve termik analiz (TG / DTG, DTA) teknikleri kullanılarak karakterize edildi. SEM-EDX ve XRD verileri saf CuxZn(1-x)O nanooksitlerin hekzagonal wurtzite yapısında kristallenmiş ve ZnO’in kristal örgüsünün içerisine bakır iyonlarının girmesiyle genişliği 100-250 nm arası çubuk ve içi boş tüp benzeri nanoyapıların oluştuğunu göstermiştir. Kaolin-CuxZn(1-x)O nanokompozitinde de bu metal oksit nanoyapıların aynı kristal ve morfolojide kaolinin tabakaları arasına sızmadan sadece kilin yüzeyinde dekore olduğu tespit edilmiştir. Kaolin ve CuxZn(1-x)O nanoparçacıkları arasındaki sinerjik etkiden ötürü en iyi fotokatalitik bozunma aktivitesine kaolin- CuxZn(1-x)O nanokompozitinin sahip olduğu ve bozunmanın yalancı birinci dereceden kinetik izlediği belirlendi. Ayrıca bu fotokatalitik bozunmaya ait optimum pH ve katalizör miktarı değerleri tespit edildi.

Synthesis, Characterization and Photocatalytic Activity of CuxZn(1-x)O Nanoparticles Decorated Kaolinite Nanocomposite

Öz:
Kaolinite-CuxZn(1-x)O nanocomposite was prepared by decoration of CuxZn(1-x)O nanoparticles on the kaolinite surface. The photocatalytic activities of raw kaolinite, bare CuxZn(1-x)O and kaolinite-CuxZn(1-x)O nanocomposite were comparatively determined by using degradation of rhodamine B from wastewater under UVA irradiation. All samples were characterized by utilizing SEM-EDX, XRD, FTIR, and thermal analysis (TG / DTG, DTA) techniques. The SEM-EDX and XRD data showed that bare CuxZn(1-x)O nanooxides formed as a rod and hollow tube-like nanostructures via copper ions have entered the ZnO lattice in the hexagonal wurtzite structure during the synthesis. These metaloxide nanoparticles were decorated on the kaolinite surface with same crystallinite and mhorphology without intercalation into kaolinite layers. The synergetic effect between kaolinite and CuxZn(1-x)O nanoparticles showed high activity and the degradation followed pseudo first order kinetics. In adition, the optimum pH and amount of catalyst were determined belong to the this photocatalytic reaction.
