Preparation, characterization and catalytic properties of polymer-supported catalysts

Không đóng trình duyệt đến khi xuất hiện nút TẢI XUỐNG

Polymers present a class of materials that play a role of importance growing in catalysis. Polymeric catalysts based on polypropylene-polyacrylic acid (PP-APA) were prepared by the two methods: co-polymerization in the presence of transition metal ions (Cu(II), Fe(III), Co(II), Mn(II) ) and soaking method. Their catalytic activity was determined by oxidation reactions of ions S2- and hydroquinone by molecular oxygen in normal condition. It’s observed that, these catalysts showed high catalytic activity, which depends on the content, nature of metal ions supported and the condition of catalytic reactions. The re-usability of this type of Me/PP-APA in oxidation of S2- and hydroquinone was also studied.
