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‐H₂, H₂ chemisorption, TPD‐NH₃ 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.

SBA-3材料负载的Ir催化剂上三氯乙烯的水相加氢脱氯

这项工作研究了二氧化硅和铝硅酸盐SBA-3负载的铱催化剂在三氯乙烯的水相加氢脱氯中的催化性能。通过XRD，BET，TPR-H ₂，H ₂化学吸附，TPD-NH ₃彻底表征了SBA-3，AlSBA-3，Ir / SBA-3和Ir / AlSBA- ₃并研究了在温和的操作条件下在间歇反应器中从水中催化去除三氯乙烯的方法。发现均匀分散的小铱纳米颗粒（约3 nm）在从氯有机化合物中催化纯化水方面具有活性。研究表明，Ir / SBA-3和Ir / AlSBA-3催化行为的差异取决于载体的性质。对于用亲水性更高且有序的AlSBA-3负载的Ir负载的Ir，可以获得从三氯乙烯中纯化水的最佳催化性能。
