Recent progress in the chemical reduction of graphene oxide by green reductants–A Mini review

Open access
Kurian, Manju·2021·Carbon Trends

Abstract

Reduced graphene oxide, the 2-dimensional sheet of sp2 carbon atoms arranged in a honeycomb structure with a minimum amount of oxygen containing groups, is a hot topic of research due to its versatile properties such as high mechanical strength, electrical conductivity, chemical properties, molecular barrier abilities and optical properties. Conventional methods for the synthesis of reduced graphene oxide involve harsh conditions such as high temperature and toxic solvents and reagents. Chemical reduction of graphene oxide using green reductants is an emerging area of research in graphene technology, considering the sustainable nature of the process. This review discusses various nontoxic, natural products such as biomolecules, biomass, waste biomass, etc. that have been reported for the green reduction of graphene oxide. The work presented here offers a perspective on the future trends for the development of green rGO and rGO based materials, profitable in applications.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ascorbic acid largely reduces hydroxyl, epoxy, carboxyl, and carbonyl functional groups on adsorbent materials.

    “Ascorbic acid largely reduces hydroxyl (–OH), epoxy (C–O–C), carboxyl (–COOH), and carbonyl (C=O) functional groups on adsorbent materials such as those used in our study20.”

    From Optimized removal of hexavalent chromium from water using spent tea leaves treated with ascorbic acid (2022) · cites this paper as [20]

    Section 3 reports that varying the amount of ascorbic acid achieved complete removal of all four named groups from graphene oxide sheets in one study. The review does not establish that this occurs on adsorbent materials generally or on the materials used by the citing authors; Section 3 also reports another study in which carbonyl and carboxyl groups were not significantly reduced.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
