Nowe podejście w rozwoju katalizatorów

①Chemical bonding method. This method is now widely used in the manufacture of polymerization catalysts. Its purpose is to solidify the homogeneous catalyst. The carrier that can be chemically bonded to the transition metal complex has some functional groups on the surface (or functional groups are attached after chemical treatment), such as -X, -CH2X, -OH groups. This kind of support is reacted with phosphine, arsine or amine to make it phosphine, arsine or amination, and then use the lone electron pair of phosphorus, arsenic or nitrogen atom on the surface to coordinate with the central metal ion of the transition metal complex. chemically bonded solid-phase catalysts, such as the manufacture of Ziegler-Natta catalysts, a carrier for bulk liquid phase polymerization of propylene.

② fibrosis method. For the manufacture of precious metal-containing supported catalysts. For example, borosilicate is drawn into glass fiber filaments, corroded with concentrated hydrochloric acid solution to become a porous glass fiber carrier, and then impregnated with chloroplatinic acid solution to carry platinum components. Depending on the practical situation, the fiber catalyst can be compressed into various shapes and required tightness, such as the catalyst used in the oxidation of automobile exhaust gas, which can be compressed into a short round tube. Carbon fiber can also be used if it is not an oxidation process. The manufacturing process of the fiber catalyst is complicated and the cost is high.
