“…Thus, HTC has been considered to be a highly feasible carbonization method to produce effective biochar for contaminant adsorption in water purification or soil remediation, renewable energy, and catalysis, as well as functional materials for electrochemical heavy metal sensing . Different sensor materials have been synthesized using hydrothermal reaction from graphene, carbon nanotubes, and metal oxides ( Table ). Biochar nano/microsphere could be formed via the following process: taking biomass precursor like cellulose and semi‐cellulose as an example, the raw material will be firstly hydrolyzed into polysaccharides, mono‐saccharides, and then soluble organic compounds.…”

The increase in release of toxic heavy metals into natural water attracts much attention due to its devastating effect on ecology and human health. The design and implementation of green electrode materials is pivotal for improving the electrochemical performance of in situ heavy metal monitoring. This work reviews various novel electrode materials and hybrid materials that improve electrochemical detection. Modified green and novel electrode materials offer better performance due to their improved deposition with wide linear and enhanced response under optimized sensing parameters. In particular, recent works related to gold, carbon materials, bismuth, and metal oxide‐based electrodes are reviewed. The environmentally friendly (“green”) characteristics, as well as their versatility and flexibility, are especially emphasized. In addition, synthesis methods and novel designs of electrode integration are highlighted. Most of the substantial achievements as well as breakthroughs in recent years are surveyed, and the challenges and prospective in this field are also identified.

A novel magnetic adsorbent Fe3O4/reduced graphene oxide‐carbon nanotubes, was prepared by one‐pot solvothermal synthesis method. It was characterized by scanning electron microscopy, X‐ray powder diffraction and vibrating sample magnetometry. The diameter of Fe3O4 microparticles was about 350 nm, which were covered by carbon nanotubes and reduced graphene oxide sheets, while carbon nanotubes inserted between the reduced graphene oxide sheets effectively prevented their aggregation. The composite had large surface area and good magnetic property, suiting for magnetic solid‐phase extraction and the determination of sulfonamides, by coupling with high‐performance liquid chromatography. Under the optimized conditions (including extraction time, amount of adsorbent, solution pH, ionic strength and desorption conditions), a good linear was achieved in the concentration range of 5–500 μg/L and the low limits of detection and low limits of quantification were 0.35–1.32 and 1.16–4.40 μg/L, respectively. The enrichment factors were estimated to be 24.72 to 30.15 fold. The proposed method was applied for the detection of sulfonamides in milk sample and the recoveries were 88.4–105.9%, with relative standard deviations of 0.74–5.38%.

“…21,22 Among those carbon nanomaterials, CNTs have been most widely used due to their rich pore structures, large specic surface areas, and surface group functionalizable. [23][24][25] Since the three-dimensional nanostructure of CNT can provide a larger electro-active surface, polymer/CNT composite modied electrodes which hold more ideal electron conduction capability and mechanical strength have been developed and applied to the sensitive and selective analysis of nucleic acid, 26,27 enzyme, 28,29 inorganic ions 30,31 and organic molecules, 32,33 showing out a wide application prospect in analytical chemistry.…”
