Adsorption of isopropanol on a nickel oxide

Adsorption isotherms of isopropanol are obtained in the temperature range of 243 to 303 K on the initial surface of nickel oxide after its treatment in high-frequency plasma in Ar and glow-discharge plasma in O2. It is found that such treatment lower the isosteric heat and differential entropy of reversible adsorption, along with the general acidity of the oxide's surface. At low degrees of filling, isotherms are described by the equation of induced adsorption. It is established that adsorbed molecules of isopropanol take negatively charged and two positively charged forms. Lewis acidic centers of various strengths can serve as adsorption centers in addition to centers of other types. © 2014 Pleiades Publishing, Ltd.
