Methacrylic Acid-Acrylamide based ZnO Hydrogel Nanocomposite Assisted Photocatalytic Decolorization of Methylene Blue Dye

Abstract

In this research, preparation of methacrylic acid-acrylamide based ZnO hydrogel nanocomposite (MAA-AM)/ZnO hydrogel nanocomposite by way of co-polymerization via used acrylate acid (AA) (or acrylate salt) (AA) or methacrylic acid (MAA)) and acrylamide (AM). Nanocomposites based on acrylate are characterized via being hydrophilic and able to retain water. Nanocomposite properties were studied using different techniques (FE-SEM, TEM, and EDX). The photocatalytic degradation of methylene blue MB dye under different conditions was studied using nanocomposite like time of irradiation, mass of catalyst (MAA- AM)/ZnO hydrogel nanocomposite, initial MB dye concentration onto photocatalytic degradation and reactivation were studied. The result increases the photocatalytic degradation with the rise weight of catalyst (MAA- AM)/ZnO hydrogel nanocomposite range (0.1–0.25 g). Too, a decrease in photocatalytic degradation was observed with an increase in MB. Observed that after reuse, ((MAA- AM)/ZnO) nanocomposite hydrogel appear photocatalytic efficiency from of the use 1 to 6 cycle 87.88 to 58.87%, showing that ((MAA- AM)/ZnO hydrogel nanocomposite surface appear good stability.
