FESEM and HRTEM analyses demonstrated the flower and hexagonal plate-like nano-structured of mixed oxides. Different mixed oxide formation, homogenous metal dispersion, textural properties were investigated using XRD, ICP-MS and BET (N2 adsorption-desorption) techniques. Nano-structured mixed oxides exhibited 2.6 wt hydrogen adsorption that were studied using temperature programmed reductionadsorption- desorption (H2-TPR/TPD) and thermogravimetric and differential thermal analysis (TGA-DTA) techniques. Investigation corresponds that morphologies, textural properties and surface energy of mixed oxides are important in hydrogen adsorption. © (2014) Trans Tech Publications, Switzerland. %D 2014 %R 10.4028/www.scientific.net/AMR.917.360 %O cited By 6; Conference of International Conference on Process Engineering and Advanced Materials, ICPEAM 2012 ; Conference Date: 12 June 2012 Through 14 June 2012; Conference Code:106208 %J Advanced Materials Research %L scholars5174 %C Kuala Lumpur %T Hydrogen adsorption capacity investigation of Ni-Co-Al mixed oxides %A M.A. Salam %A S.
