Emerging Sustainable Nanomaterials and their Applications in Catalysis and Corrosion Control

Background: The different field of chemistry needs various greener pathways in our search toward attaining sustainability. True sustainability comes through circularity. Circular processes i.e., circular economy, circular chemistry, etc. are the only logical solutions for all challenges/ issues related to sustainability. Chemistry of matter changes with size. Nanoscale materials thus show magical properties and have a broad range of applications. Objective: Nanomaterials always fascinate researchers because of their unique and novel properties. Engineered nanomaterials hold great promise for catalysis, corrosion control, medicine, electronics, environmental remediation, and other fields. But when the nanomaterials or any new/novel materials are synthesized without considering environmental impacts at the beginning of the process, their long-term effects could undermine those advances. Sustainable nanomaterials have great capability to overcome the challenges associated with engineered nanomaterials. Presently, sustainable materials are needed to sustain life on earth. Size and shape controlled synthesis of nanomaterials is challenging to explore the various applications of nanomaterials. Conclusion: Application of nanomaterials in catalysis and protective coating of metals to prevent corrosion make it more sustainable. Present article briefly reviewed the fundamental aspects of nanomaterials, sustainable approaches of nanomaterials synthesis, and their sustainable applications i.e., catalysis and corrosion control.
