Bottom-up fabrication of two-dimensional carbon nitride and highly sensitive electrochemical sensors for mercuric ions

Sadhukhan, Mriganka, Barman, Sudip·2013·Journal of Materials Chemistry A

Abstract

We report microwave assisted bottom-up fabrication of flat two-dimensional carbon nitride from formamide (HCONH2). Microwave irradiation of HCONH2 produces carbon nitride dots (CNDs) which are used as precursors for synthesis of carbon nitride (C3N4). The two-dimensional (2D) carbon nitride sheets are formed by evaporation induced self-assembly and condensation of CNDs on a solid substrate. The drying of CND solution generates different morphologies such as 0D carbon nitride quantum dots, 2D carbon nitride sheets and 3D carbon nitride, depending on the concentration of CNDs. The carbon nitrides are well characterized by TEM, AFM, SEM, XRD, XPS, FT-IR, FT-Raman Spectroscopy and TGA, CHN analysis. In addition, the C3N4 modified glassy carbon electrode can be used as a highly sensitive electrochemical sensor for mercuric ions in aqueous solution. The lower detection limit of Hg2+ is found to be 9.1 × 10−11 M, which is far below the WHO guideline for drinking water (10−8 M). The simultaneous electrochemical detection of Pb2+, Cu2+ and Hg2+ using a C3N4 modified GC electrode is also described.

Verification

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

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.
