A two-step polymerization technique is introduced to synthesize polyacrylamide/polyacrylate interpenetrating network (PAM/PAC IPN) hydrogels. The swelling ratio of the IPN hydrogel increases with the increase of the PAC content in PAM/PAC, and is smaller than the traditional PAM or PAC superabsorbents. A non-Fickian mechanism is observed in the swelling process, and the swelling changes from non-Fickian...
Pt modified TiO 2 loaded on natural zeolites (Pt–TiO 2 /zeolites) was prepared by sol–gel technique and photoreductive deposition method. The photocatalysts were characterized by UV–vis absorption spectrum, FTIR spectrum, BET and X-ray diffraction. Their photocatalytic activities were examined by the photocatalytic decolorization of methyl orange solution under UV light irradiation...
