Abstract

   Bakır asetat monohidratın
(Cu(CH₃COO)₂.H₂O) termal bozunma yolu ile
bakır oksit (CuO) sentezi hava ortamında izotermal olmayan şartlar altında 10°C
dak^-1’lik ısıtma hızıyla TG-DTG/DSC
cihazında incelendi. 25°C’den 900°C’ye kadar termal bozunma prosesinin üç
adımda gerçekleştiği görüldü (iki kütle kayıp bölgesi ve bir küçük kütle kazanç
bölgesi). 200, 300, 400°C sıcaklıklarda elde edilen ürünler X-ışını kırınımı
(XRD), Fourier dönüşümü kızılötesi spektroskopisi (FTIR), Taramalı elektron
mikroskobu (SEM), ve Enerji dağıtıcı spektroskopisi (EDS) analizleri ile
karakterize edildi. XRD sonuçları CuO nanopartiküllerin monoklinik kristal
yapıya sahip olduğunu göstermektedir. SEM
görüntüleri CuO nanopartiküllerinin şekil olarak küresel olduğunu
göstermektedir. CuO nanopartiküllerin boyutu, tavlama sıcaklığındaki bir artışla
azaldı.

SYNTHESIS OF COPPER OXIDE (CuO) FROM THERMAL DECOMPOSITION OF COPPER ACETATE MONOHYDRATE (Cu(CH3COO)2.H2O)

Abstract

   The synthesis
of copper oxide (CuO) via the thermal decomposition of copper (II) acetate
monohydrate (Cu(CH₃COO)₂.H₂O) in air
atmosphere was investigated at TG-DTG/DSC apparatus
with the heating rate of 10°C min^-1 under non-isothermal conditions
from 25 to 900°C. It was seen from TG-DTG/DSC analyzes that the thermal
decomposition process consists of three main steps (two mass-loss regions and a
tiny mass-gain region). The obtained products at 200, 300, 400°C
temperatures  were characterized by X-ray
diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning
electron microscopy (SEM) and Energy disperse spectroscopy (EDS) analysis. The
XRD results show that the CuO nanoparticles having the monoclinic crystal
structure. The SEM images showed that CuO nanoparticles were spherical in
shape. The size of CuO nanoparticles decreased with an increase in annealing
temperature.
