Mesoporous carbon decorated with MIL-100(Fe) as an electrochemical platform for ultrasensitive determination of trace cadmium and lead ions in surface water

Hematite nanoparticle decorated MIL-100 for the highly selective and sensitive electrochemical detection of trace-level paraquat in milk and honey

“…Furthermore, it is used in photocatalytic applications owing to its excellent optical properties [26] and as a carrier for drug delivery applications [27]. Yelin Zhu et al [28]. synthesized MC@MIL-100(Fe) by in situ growth of MIL-100(Fe) on a carbon surface for the detection of heavy metal ions in water with satisfactory detection limits of 0.18 and 0.15 μgL − 1 for Cd(II) and Pb(II), respectively.…”

MoS2 nanosheets grown on bowl-shaped hollow carbon spheres as an efficient electrochemical sensor for ultrasensitive determination of nephrotoxic aristolochic acids in Chinese traditional herbs

“…Moreover, the background current of MoS 2 –BHCs/GCE was smaller than that of BHCs/GCE, indicating that MoS 2 loaded on the surface of the BHCs reduced the capacitive current and enhanced the sensitivity of the sensor. 36 Based on the Nicholson and Shain analysis, 37 the electron transfer rate constant can be calculated from the CV, which is also a determining factor in describing the electrode process. 38 Fig.…”

Recent advances in the modification of electrodes for trace metal analysis: a review

“…Table S4 in the ESI † summarizes the main findings of the research studies published in the last five years regarding the use of different metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) as modifiers for various types of electrodes employed in the determination of trace heavy metals. Several MOFs 42,53,116,[150][151][152][153][154]164,177,201,208,209,212,216,236,237,[279][280][281][282][283][284][285][286][287][288][289][290][291][292][293][294][295][296][297] and COFs 198,[298][299][300][301][302] have been employed as modifiers for different types of electrodes in combination with other materials. MOFs are 1D, 2D, or 3D network like structures, highly ordered crystalline materials formed by self-assembly of metal ions or clusters and organic ligands through coordination bonds.…”
