Abstract This work investigates the catalytic properties of silica and aluminosilicate SBA‐3 supported iridium catalysts in aqueous phase hydrodechlorination of trichloroethylene. SBA‐3, AlSBA‐3, Ir/SBA‐3 and Ir/AlSBA‐3 were thoroughly characterized by XRD, BET, TPR‐H 2 , H 2 chemisorption, TPD‐NH 3 and investigated in catalytic removal of trichloroethylene from water in batch reactor under mild operation conditions. Uniformly dispersed small iridium nanoparticles (∼3 nm) was found to be active in catalytic purification of water from chloroorganic compound. The studies showed that the differences in catalytic behavior of Ir/SBA‐3 and Ir/AlSBA‐3 depended on the properties of the support. The best catalytic properties in purification of water from trichloroethylene was obtained for Ir supported on more hydrophilic and ordered AlSBA‐3 with acid sites.
