The novel and efficient reduction of graphene oxide using Ocimum sanctum L. leaf extract as an alternative renewable bio-resource

Abstract

The efficient, rapid, bio-inspired synthesis of reduced graphene oxide (rGO) nanosheets was explored using green leaf extract of Ocimum sanctum L. (Tulsi leaves). This mild biorenewable reducing agent containing eugenol, ascorbic acid, and polyols also acts as a stabilizer for the prepared rGO.

Improvement on mechanical and flame retardancy behaviour of bio-exfoliated graphene-filled epoxy/glass fibre composites using compression moulding approach

“…Suhasini et al, used Ocimum sanctum (Tulasi leaf) extract to reduce graphene oxide and attain better reduction in synthesizing reduce graphene oxide. In some studies, wild carrot and Aloe vera extracts were used as reducing agent, and the reduce graphene oxide exhibits better performance in photo catalyst and electrochemical applications [23]. Abutilon indicum (Tamil: Thuthi), a medicinal plant, which are abundantly available in southern region of India.…”

Facile, cost-effective and eco-friendly synthesis of carbonyl-rich partially reduced graphene oxide using glucose as a sole precursor

“…The C/O ratio of the sample is 2.1, which suggests the formation of graphene oxide [21] (for rGO C/O > 7 [30]). Whereas, XRD result suggested the formation of rGO and we also didn't observe any diffraction peak around 10°, which is generally observed in the case of oxygen-rich graphene derivatives [32]. The contrast in XPS and XRD results is because the majority of the oxygen in the sample is of carbonyl functional groups that exist at the plane edge.…”

“…In the FTIR spectrum ( Fig. 2a), strong characteristic peak at 1534 cm −1 due to C=C stretching skeletal vibrations of aromatic domains [32] and peak at 1680 cm −1 corresponding to C=O stretching vibrations in carbonyl groups [10] confirms the formation of carbonyl-rich partially reduced graphene oxide. Peaks at 1305 cm −1 , 1207 cm −1 , and 1028 cm −1 are due to C-O bending vibrations, epoxy C-O-C stretching vibrations and alkoxy C-O stretching vibrations [20], respectively.…”

“…Residual CO 2 adsorbed on to the sample results in a small peak at 2333 cm −1 [34]. 1403 cm −1 peak is attributed to O-H bending vibrations incurred by the angular deformation of water adsorbed on the sample [32]. FTIR result (Fig.…”

Hematological and Biochemical Investigations of Green Synthesized Reduced Graphene Oxide Carbon Nanoparticles on Acetaminophen Induced Male Albino Rats.

“…In our laboratory we have prepared reducedgraphene oxide carbon nanoparticles from graphene oxide by using modern green synthetic approach 29,30 . Root extracts of Asparagus racemosus (commonly known as Shatamuli) ( Figure 1) has been used as reductant phytochemicals for this green conversion.…”
