Fig. 1 Heating procedure of catalyst precursor.

The concentration and reactivity of the oxidation sites, determined from isotopic transient experiments, appear to depend on the procedure of catalyst preparation.

Also, thermogravimetric analysis demonstrated that the residual water adsorption value in K2PdCl4 Cu(NO3 2 KBr H2O/3H-CLI after its air-drying at 110 °C (the temperature used in our procedure of catalyst preparation) was 3.1 mmol g−1, and this value, according to the water vapor isotherm, corresponded to ( a_{{{text{H}}_{2} {text{O}}}} ) = 0.26 (i.e. relative humidity, RH, of 26%).

During the preparation procedure of catalysts the drying temperature does not affect significantly the catalytic area while increasing calcination temperature leads to lower surface areas.
