Abstract

Biomass is a promising raw material for synthesizing heteroatom-doped carbon due to its cheap cost and easy availability. Herein, we fabricate nitrogen and sulfur codoped carbon (NSC) with extremely high specific surface areas (BET surface areas of 3015 m 2 /g) by employing human hair as the precursor. The graphitization degree, N/S doping content, and pore structures of NSC can be easily modulated by the heat treatment conditions. Besides, NSC obtained at 800 °C (NSC-800) even outperforms most traditional metal-based catalysts under the same conditions for BPA degradation. Influences of various operating parameters (NSC, Oxone, and BPA concentration) and the inorganic salts/humic acid (HA) on BPA degradation are comprehensively studied. Furthermore, quenching experiments and electron paramagnetic resonance (EPR) measurements prove that 1 O 2 should be the main active species generated from PMS activation, and the contribution of •OH/SO 4 •– is very limited. This work is expected to arouse more interests about biomass-derived carbon for PMS activation and environmental remediation.

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?

  • In that human-hair-derived N,S-doped biochar, the slight S doping (1.04 at.%), mainly thiophene S on edge sites rather than inert oxygenated S, acted as a co-doping agent to enhance electrochemical carbocatalysis.

    “It is noteworthy that the slight doping of S contents (1.04 at.%), mainly consisting of thiophene S on the edge sites rather than inert oxygenated S, was also emphasized in this research as co-doping agent to enhance electrochemical carbocatalysis.”
  • A human-hair-derived N,S-doped porous biochar fabricated at 800 °C outperformed most traditional metal-based catalysts for PMS activation in bisphenol A degradation, with incorporated graphitic N circulating electron flow and adjusting electron density of adjacent carbon atoms.

    “A human-hair-derived N, S-doped porous biochar was also successfully fabricated under high temperature (800 °C), and outperformed most traditional metal-based catalysts towards PMS activation for bisphenol A degradation, wherein the incorporated graphitic N exhibited good function to circulate electron flow and adjust the electron density of adjacent carbon atoms.161”

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.
