Özet:

 In this study, the synthesis and electrochemical application of boron nitride quantum dot BNKN  reduced graphene oxide rGO hybrid structure, which is a new electrode material to be used for supercapacitors, is investigated. BNKN is recommended because it has the same crystal structure as graphene oxide GO, and so the hybrid structure of BNKNrGO exhibits excellent electrical characteristics. BNKN, a hexagonal boron nitride h-BN nanostructure-based hybrid material, has appeared in recent studies due to its thermal stability and electrical conductivity, while graphene is frequently preferred in supercapacitor studies because it has a large specific surface area. In addition, the main reason for adding different heterostructures to this structure to improve the capacitance value of graphene is; changing the electron donating properties of carbon materials has been made a priority. Therefore, the specific capacitance value was measured, considering that the BNKNrGO hybrid electrode to be used in supercapacitors would increase the electrochemical activity. A high capacitance value of 207.5 Fg was found at 5 mvs-1 scanning speed of the BNKNrGOH hybrid structure as a result of electrochemical investigations. At 10,000 cycles, it also demonstrated a cyclic stability performance of 88.9.

 Bu çalışmada süperkapasitörler için kullanılacak yeni bir elektrot malzemesi olan bor nitrür kuantum nokta BNKN  indirgenmiş grafen oksit rGO hibrit yapısının sentezini ve elektrokimyasal uygulamalarına yer verilmiştir. BNKNnin, grafen oksit GO ile aynı kristal yapıya sahip olması ve bunun sonucunda BNKNrGO hibrit yapısının çok iyi elektriksel özellik gösteriyor olması tercih edilme sebeplerindendir. Hekzagonal bor nitrür h-BN nanoyapı tabanlı hibrit malzeme olan BNKN, termal kararlılıkları ve elektriksel iletkenlikleri sebepleriyle son yıllardaki çalışmalarda karşımıza çıkarken, grafen ise geniş spesifik yüzey alanına sahip olduğu için süperkapasitör çalışmalarında sıklıkla tercih edilmektedir. Ayrıca, grafenin kapasitans değerini geliştirmek için bu yapıya farklı nanomalzemeler eklenmesinin ana sebebi karbon malzemelerin elektron verici özelliklerinin geliştirilmesidir. Bundan dolayı, süperkapasitörlerde kullanılacak BNKNrGO hibrit elektrotunun elektrokimyasal aktiviteyi arttıracağı düşünülerek spesifik kapasitans değeri ölçülmüştür. Elektrokimyasal çalışmalar sonucunda, BNKNrGOH hibrit yapısının 5 mvs-1 tarama hızında 207.5 Fg yüksek kapasitans değeri elde edilmiştir. Ayrıca 1.000 döngüde 88.9luk döngüsel stabilite performansı sergilemiştir.
