<p>The catalytic process of interaction between the propylene and H<sub>2</sub>O over bimetallic Rh-Ir/C-catalysts of clusters type, has been studied. The possibility of the process interaction between C<sub>3</sub>H<sub>6</sub> and H<sub>2</sub>O according to and against Markovnikov rule are showed. The structure and state of Ru-Ir/C-catalysts surfaces were investigated by using electron microscopy.</p>
