Abstract
CdO nanoparticles have been prepared by the thermal decomposition of a precursor complex. A simple and cost effective room temperature synthetic technique allows the preparation of the precursor complex from hexamethylenetetramine and cadmium nitrate in ethanol. The precursor, characterized by elemental analysis, mass spectrometry, Fourier transform infrared spectroscopy (FTIR), and thermal gravimetric analysis, had the composition [{Cd(HMTA)(NO3)2(H2O)2}n]. It was calcined at 500 oC for 2 h, and the cadmium oxide nanoparticles obtained was characterized by X-ray diffraction (XRD), scanning electron microscopy, high resolution transmission electron microscopy (HRTEM), Nitrogen adsorption and physisorption, and Selected Area Electron Diffraction (SAED). XRD shows that the CdO obtained is pure and crystalline. The particles obtained had a cubic morphology and are mesoporous.
Highlights
Over the past few decades, nanomaterials, including metal oxide nanoparticles, have received enormous scientific attention because of their interesting novel and improved physico-chemical and biological properties as a result of size reduction to the nano-regime (Devan, Patil, Lin, & Ma, 2012)

Summary
Over the past few decades, nanomaterials, including metal oxide nanoparticles, have received enormous scientific attention because of their interesting novel and improved physico-chemical and biological properties as a result of size reduction to the nano-regime (Devan, Patil, Lin, & Ma, 2012). Their unique physical properties that are size- and shape-dependent, render them applicable in many fields such as optics, magnetism, catalysis, electricity, energy production and storage, environmental remediation, antimicrobial agents and drug delivery Wang, & Zha, 2009; Jolivet et al, 2010). 2007; Ghoshal et al, 2009; Tadjarodi & Imani, 2011b; Giribabu, Suresh, Manigandan, Stephen, & Narayanan, 2013; Kalpanadevi, Sinduja, & Manimekalai, 2013)
