Abstract

We have studied the effect of preparation methods, under argon gas and in the air environment, on the cobalt oxide formation of CoPt nanoparticles by the polyol process. The formation of cobalt oxide for both samples was investigated by the x-ray diffraction (XRD) method and cobalt oxide peaks are observed in the air prepared sample. Rietveld refinement analyses revealed that all samples exhibit a chemically distorted cubic crystal structure. The average particle size was determined

Özet

Polyol yöntemi ile hazırlanan CoPt nanoparçacıklarının üzerine oluşturulan kobalt oksit oluşumunun argon gazı ve hava ortamında etkilerini çalıştık. Her iki numune için kobalt oksit oluşumu, x-ışını kırınımı (XRD) yöntemi ile araştırıldı ve hava ile hazırlanan numunede kobalt oksit oluşumu gözlendi. Rietveld düzeltme analizleri, tüm numunelerin kimyasal olarak düzenli olmayan bir kübik kristal yapı sergilediğini ortaya çıkarmıştır. Ortalama parçacık boyutu, taramalı elektron mikroskopisi (SEM) ile
