CuO Nanoparçacıkların Kolay ve Amorf Yapıda Sentezi

Bakır oksit (CuO) nanoparçacıkları, sıvı bir ortamda ark deşarj yöntemi ile başarılı bir şekilde sentezlendi. İki bakır elektrot arasında ark boşalması gerçekleşerek üretimi tamamlanan bakır oksit nanoparçacıkların morfolojisi ve Kristal yapısı ayrıntılı bir şekilde incelenmesi yapıldı. Elektron mikroskobu incelemeleri sonucunda üretilen CuO nanoparçacıkların 10-50 nm aralığında nominal çaplarda düzensiz şekilli olduğu görülmektedir. XRD sonuçları ise sentezlenen parçacıkların herhangi bir safsızlık olmadan sadece CuO piklerini içerdiğini göstermektedir. Sonuçlara göre tek fazlı CuO nanoparçacıkların üretilmesi için ark deşarj yöntemi basit, ucuz ve esnek bir yöntemdir.

FACILE AND TEMPLATE-FREE SYNTHESIS OF CuO NANOPARTICLES

Copper oxide (CuO) nanoparticles were synthesized successfully by arc discharge methodin an aqueous medium. Arc discharge was ignited between two copper electrodes and an exhaustivecharacterization of morphology and crystalline structure of the drawn up copper oxide nanoparticleswere studied. Electron microscopy analyses revealed that the grown CuO nanoparticles are irregularlyshaped with nominal diameters in the interval of 10-50 nm. XRD results show the as-synthesizedparticles contain only CuO peaks without any impurities. The results procure a simple, cheap andresponsive method for preparing single-phase CuO nanoparticles.
