“…In a drive for furthering the advantages of this method, several reductants derived from renewable biological sources, such as, ascorbic acid, 19,115 Azadirachta indica extract, 116 atriplex halimus leaves extract, 117 clinacanthus nutans (leaf extract), 118 Cetraria islandica ach. extract, 6 eclipta prostrata (phytoextract), 56 Leucas aspera (Thumbe, a leaves extract), 119 terpenoids and polyphenols (vernonia amygdalina extract), 35 Chenopodium album (vegetable extract), 120 olea europaea (olive extract), 121 Murraya koenigii (leaf extract), 122 and green tea extract, 114,[123][124][125] have been reported for RGO synthesis (Table 3).…”

“…Other reduction conditions in combination with ascorbic acid, such as stirring (rate and mode), high GO : reductant ratio, sonication, and alkaline pH, also shorten the reaction time from 48 to ∼1 h. 112 The use of biologically derived reductants is an interesting progress towards the sustainability of graphene-based materials, since both GO and RGO can also be biologically derived. [127][128][129] This is a step near the elimination of expensive, explosive, toxic and carcinogenic chemicals; 122,124 such as hydrazine (and its derivatives), 43,58 and sodium borohydride; 130 that harm the environment. This is a highlight of the tremendous potential of biologically derived reductants not only due to their biocompatibility nature, but also because the approach is a suitable standardisation step in future research.…”

“…Parthipan et al [69,84] investigated the photocatalytic activity of rGO biosynthesized from Phyllanthus emblica fruit extracts (PErGO) and Murraya koenigii leaf extract (MKrGO) against MB, MO, and mixed (MB + MO) dye solutions when exposed to sunlight and UV light. PErGO treated with a mixed dye solution (MB + MO) and exposed to sunlight demonstrated degradation efficiencies of 9% and 91% for the MO and MB dyes, respectively.…”

Graphene, a remarkable material, is ideal for numerous applications due to its thin and lightweight design. The synthesis of high-quality graphene in a cost-effective and environmentally friendly manner continues to be a significant challenge. Chemical reduction is considered the most advantageous method for preparing reduced graphene oxide (rGO). However, this process necessitates the use of toxic and harmful substances, which can have a detrimental effect on the environment and human health. Thus, to accomplish the objective, the green synthesis principle has prompted researchers worldwide to develop a simple method for the green reduction of graphene oxide (GO), which is readily accessible, sustainable, economical, renewable, and environmentally friendly. For example, the use of natural materials such as plants is generally considered safe. Furthermore, plants contain reducing and capping agents. The current review focuses on the discovery and application of rGO synthesis using extracts from different plant parts. The review aims to aid current and future researchers in searching for a novel plant extract that acts as a reductant in the green synthesis of rGO, as well as its potential application in a variety of industries.

Thus, to accomplish the objective, the green synthesis principle has prompted researchers worldwide to develop a simple method for green reduction of graphene oxide (GO), which is readily accessible, sustainable, economical, renewable, and environmentally friendly in nature. For example, the use of natural materials such as plants is generally considered safe. Furthermore, plants contain reducing and capping agents. The current review will focus on the discovery and application of rGO synthesis using extracts from a variety of different parts of the plant. The review aims to aid current and future researchers in their search for a novel plant extract that acts as a reductant in the green synthesis of rGO. The review aims to assist current and future researchers in their research for a novel plant extract that acts as a reductant in the green synthesis of rGO as well as their potential applications in a variety of industries.
