Sustainable Graphene Production: New Insights into Cannabis sativa Engineered Carbon Dots Based Exfoliating Agent for Facile Production of Graphene

摘要

The direct exfoliation of graphite (Gr) produces high-quality graphene (G) having enormous industrial applications. Exploring sustainable sources as an exfoliating agent offers advantages in terms of cost and ease of production. Herein, sustainably sourced Cannabis sativa engineered carbon dots ([email?protected]) were used as an exfoliant for direct exfoliation of Gr into G ([email?protected]). The present method opens a new avenue toward exploring a zero-dimensional carbon material (0D) for exfoliating Gr (3D) to G (2D). High-temperature sonication (～60 °C) facilitates the exfoliation process by disrupting π–π interactions between Gr sheets. The [email?protected] stabilizes the exfoliated sheets via electrostatic interaction into [email?protected] The Raman spectroscopy confirms successful exfoliation and formation of few-layer graphene sheets, whereas atomic force microscopy reveals the presence of [email?protected] on the [email?protected] sheets. [email?protected] shows excellent stability over 1 month under various harsh conditions, confirming the role of [email?protected] in the stabilization process. Interestingly, [email?protected] exhibit antibacterial nature by hindering the growth of bacteria.
