STRONG METAL-SUPPORT INTERACTIONS hydrogen adsorption

Wang S-Y, Moon SH, Vannice MA (1981) The effect of SMSl (strong metal-support interaction) behavior on CO adsorption and hydrogenation on Pd catalysts 11. Kinetic behavior in the methanation reaction. J Catal 71 167... [Pg.151]

H-free surfaces. On hydrogen-free surfaces, the formation of terminal-CO species reveals the involvement of electron deficient (perturbed) Ni° metal sites. These sites can be generated consequently to (i) strong interactions of atomically dispersed (isolated) metal atoms with the support, and/or (ii) through-oxygen electron-exchange interactions with adjacent Ni impurity sites. Hence, the adsorption is weakened and the IR vCO frequency shifted upwards. As shown by Pearson [33], both incomplete reduction of metal ions and atomic dispersion of metal atoms are quite likely on surfaces of the electronically hard alumina. [Pg.575]
