Green synthesized metal oxide nanoparticles offer suitable alternatives as low-cost, eco-friendly and versatile materials for wastewater remediation. In this work, we presented an overview on green techniques for the synthesis of metal oxide nanoparticles from agricultural biomass, algae, microorganisms and natural polymers for organic pollutants degradation. The unique and potential features of the materials such as optical and electronic properties, diverse surface chemistry, redox activities, high porosity, thermal and mechanical stabilities, and non-environmental toxicities have been emphasized. Overview on their photocatalytic efficiency towards degradation of dyes, pharmaceuticals, phenols, herbicides and pesticides, polycyclic aromatic hydrocarbons and other spectrum of organic pollutants have been presented. Modifications for improvement of the materials performance using techniques such as metal doping, bimetallic metal oxide, heterojunctions with carbon-based, organic polymers, carbon dots and other functionalized materials have elaborated. Mechanisms governing the photocatalytic process has been elucidated. The suitability of the materials for the photocatalytic application has been emphasized. The prospects and challenges regarding the materials application have been highlighted. Lastly, innovative approaches for the improvement of the efficiency of the materials for real wastewater applications have been proposed.
