dc.description.abstractBu çalışmada, kitosan-guar sakızı kompozitinden (CS-GG) oluşan son derece kararlı biyobozunur mikro kapsüller, katalizör desteği olarak hazırlandı. Daha sonra, paladyum partikülleri, herhangi bir toksik indirgeyici madde kullanmadan tasarlanan destek üzerine başarıyla dekore edildi (Pd NP@CS-GG). CS-GG ve Pd NP@CS-GG’lerin yapısal karakterizasyonu farklı analitik tekniklerle yapıldı ve paladyum nanopartiküllerinin boyutunun 23-48 nm aralığında değiştiği tespit edildi. Daha sonra, Pd NP @ CS-GG'nin katalitik aktivitesi, mikrodalga ısıtma kullanılarak çözücüsüz ortam altında çeşitli biaril bileşiklerin üretiminde değerlendirildi. Pd NPs@CS-GG, çeşitli aril halojenürlerin iyi reaksiyon verimleriyle istenilen biaril bileşiklerine dönüştürülmesinde yüksek katalitik performans gösterdi. Ayrıca, Pd NPs@CS-GG'nin, en az yedi kez tekrar kullanımı nedeniyle uzun yaşam süresine sahip bir katalizör olduğu bulundu.en_US
dc.description.abstractIn this study, highly stable biodegradable microcapsules, which are composed of chitosan-guar gum composite (CS-GG), were prepared as catalyst support. Then, palladium nanoparticles were successfully decorated on the designed support without using any toxic reducing agent (Pd NPs@CS-GG). Structural characterizations of CS-GG and Pd NPs@CS-GG were carried out by different analytical techniques and it was detected that the size of palladium nanoparticles changed in the range of 23-48 nm. Then, the catalytic activity of Pd NPs@CS-GG was evaluated in the fabrication of various biaryl compounds under solventless media using microwave heating. Pd NPs@CS-GG showed high catalytic performance in the conversion of various aryl halides to desired biaryl compounds with good reaction yields. Moreover, it was found that Pd NPs@CS-GG was a catalyst having long life time because of its reuse at least seven times.en_US
