Adsorbed water has been found to affect greatly hydrogen thermodesorption from Rh/Al/sub 2/O/sub 3/ catalysts. Water formed during H/sub T/-O/sub T/ titration and that introduced from outside give eventually analogous changes in hydrogen temperature-programmed desorption curves. As the amount of water increases the amount of desorbed hydrogen initially increases and then decreases. It seems that changes in hydrogen thermodesorption are a symptom of metal-support interaction. A model of this interaction has been suggested.
