Composite metal oxide samples were synthesized using all natural ingredients by a special slow combustion process. The samples thus prepared have very good adsorbing capacity for both liquids and vapor and gases. The adsorption seems to be a function of the natural ingredients as well as the mode of synthesis. The samples synthesized via the special slow process have unique properties as opposed to those made by normal combustion.

A detailed investigation to decode the origin of these unique properties has been undertaken by study of its composition, adsorption isotherm, particle size by various instrumental techniques including Scanning Electron Microscopy. The results will be discussed in our presentation.
