A review on catalytic reduction/degradation of organic pollution through silver-based hydrogels

Abstract

Various challenging pollutants are produced in the environment by organic materials of diverse industries including leather, paint, and textile. Nowadays, it is vital to develop efficient manners regarding the fundamental issues and removing pollutants. Such pollutants can be effectively removed from the environment through heterogeneous catalysts. Recently, a huge deal of interest has been attracted by hydrogel-based metal catalysts as heterogeneous and efficient catalysts. In this regard, silver with its unique features is suitable for environmental remediation. Hence, the present review deals with summarizing the present advances in the synthesis of silver-based hydrogel catalysts, as well as their applications for environmental remediation. Some advantages have been proposed using silver-based hydrogel catalysts suggested including high catalytic ability, reusability, easy work-up, and simple synthesis.
