HYDROTHERMAL SYNTHESIS OF NANOSTRUCTURED MIXED OXIDES OF COPPER, ZINC AND ALUMINIUM AT DIFFERENT TEMPERATURES

Mixed oxides of copper, zinc and aluminium was synthesized hydrothermally and the effect of crystallization temperature was investigated onproducts physiochemical properties. The sampleswere synthesized at 140, 160, 180 and 200°C for 6 h crystallization time. Hydrothermally synthesized nanocomposites crystallinity was studied using XRD analysis which proved crystallinity variation by temperature. The crystallinity was enhanced byincreasing the temperature to 160°C and then fell by increasing temperature to 200°C. FESEM imaging utilized for morphological studies. The imagesshowed particles morphology variation and narrow size distribution and nano-scale particles for CZA synthesized at 180°C. BET surface area showedsimilar trend to XRD. FTIR spectroscopy inagreement with XRD pattern confirmed metal oxide formation
