Preparation, Characterization and Photocatalytic Degradation Studies of an Acrylic Acid-acryl Amide based TiO2 Hydrogel Nanocomposite: Real Samples of Pollutants Dyes

In this study, preparation of (AAc-AM)/TiO2 hydrogel nanocomposite. This hydrogel was prepared by copolymerization. Acryl amide (AM), acrylic acid (AAc) is an absorbent material of great use in the preparation of hydrogels, Where hydrogels based on acrylate are characterized by being hydrophilic and having the ability to retain water. The properties of nanocomposite were studied using several techniques (FESEM, XRD, and TEM). The photocatalytic degradation of Congo red (CR) under UV irradiation has been studied. The utilization of (AAc-AM)/TiO2 hydrogel nanocomposite as a catalyst in the photocatalysis process under several optimum conditions. The eff ect of the parameter contains the mass of the (AAc-AM)/TiO2 hydrogel nanocomposite catalyst and the concentration of Congo red (CR). Through the data, the photocatalytic activity increases by increasing the hydrogel nanocomposite mass from 0.1–0.3 g. Also, a decrease in photocatalytic effi ciency was observed with an increase in dye concentration. Observed that after re-use, (AAc-g-AM)/TiO2 hydrogel nanocomposite paper photocatalytic effi ciency from of the 1 cycle use 77.99 to 60.12% of 6 cycle use repeated to show that (AAc-g-AM)/TiO2 hydrogel nanocomposite surface appear good stability.
