A nanoscale Nd-based metal-organic framework electrochemical sensor for rapid detection of Rhodamine B

Highly catalysis amplification of MOFNd-loaded nanogold combined with specific aptamer SERS/RRS assay of trace glyphosate

“…Compared to those of MOF Nd , the infrared peaks of Au@MOF Nd did not change significantly, which might be due to the fact that the loading of AuNPs did not significantly change the structure of MOF Nd . The powder XRD patterns of MOF Nd and Au@MOF Nd show that the main diffraction peaks of MOF Nd appear at around 9.9, 10.6, 11.4, 12.8, 18.4, 21.2, 23.1, and 24.5, which is consistent with previous reports in the literature, 27 indicating that the prepared MOF Nd can be used as a powder. Compared with MOF Nd , Au@MOF Nd has no AuNP diffraction peaks, which may be attributed to the small particle size of the loaded AuNPs; the peaks of Au were masked by the strong diffraction peaks of MOF Nd (Fig.…”

“…However, the neodymium metal-organic framework (MOF Nd ) has several advantages, such as large specific surface area, high porosity, which is conducive to the loading of nanoparticles, and a preparation method that is easy to operate and consumes less organic solvent. 27,28 Therefore, it is significant to utilize MOF Nd as a carrier for the preparation of new MOF composite nanomaterials. In this paper, a MOF Nd -loaded nanogold (Au@MOF Nd ) nanocatalyst was prepared, and a novel SERS/ RRS dual-mode method for the determination of trace GLY was established by combining the Au@MOF Nd catalytic indicator reaction with the Apt reaction.…”

A review on development of metal–organic framework-derived bifunctional electrocatalysts for oxygen electrodes in metal–air batteries

“…0D MOF composites can be created in a variety of methods, but most of them include employing MOFs as carriers for already-formed NPs or as carriers by themselves that use templates to create NPs on their surfaces. 103,104…”

A designed miniature sensor for the trace level detection and degradation studies of the toxic dye Rhodamine B

“…Table 1 presents a comparison of the RhB sensing performance of our designed sensor with reported sensors. [39][40][41][42][43][44][45][46][47][48][49][50] Hence, GCE modied with functionalized multiwalled carbon nanotubes is a promising tool for the trace level detection of Rhodamine B dye.…”
