Abstract

With increasing emphasis on sustainable development, efforts for the synthesis of next-generation materials increased with the objective of utilizing them in the domains of energy generation and mitigation of greenhouse gases. Nanomaterials are one such area of study that has been a tremendous focus of research. However, large-scale manufacturing and usage of nanomaterials also entail their environmental impacts during operations and end-of-life disposal. With lacking disposal infrastructure, nanomaterials synthesized for CO2 sequestration have the potential to create damaging impacts on the ecology. This chapter presented a comprehensive analysis of recent developments in nanomaterials for CO2 capture and elaborated on their concomitant issues. It discusses liquid, metal-based, and carbon-based nanomaterials, and presents a scientific review upon their toxicities for humans, flora, and fauna. Moreover, the chapter also presented pertinent effects of nanomaterials on aquatic life, through their food chains, thus deteriorating aquatic cycles.
