Exploring the Potential of Carbon Based Materials in Air Purification

The deteriorating air quality possessed serious health concerns among human beings and displayed damaging impact on our ecosystem. Thus converting adverse atmospheric particulate materials to high valued carbon based nanomaterials (CBNs) with photocatalytic properties in air purification has gained significant interest among researchers. This review highlights the different methodological aspects of transforming waste atmospheric particulates into useful CBNs. The review begins with a special emphasis on the synthesis and mode of action of CDs on air pollutants such as volatile organic compounds, particulate matter and many toxic gases. Various mode of synthesis of CBNs along with mechanisms used for air purification such as adsorption has also been explored in this review. The synergistic effects of combining CBNs with other materials such as TiO2 and graphene have also explored. The feasibility of prepared CBNs in air purification processes involving the photocatalytic conversion of toxic air particulates have also been discussed in this review. The current study also highlights the sensory performance of CBNs. This exclusive study will surely assist a new opportunity in mitigating the issues related to air pollution and will improve the efficacy in environmental remediation activities for a clean and safe ecosystem.
