“…The XRD pattern of CuFe (Figure a) showed reflection peaks at 12.77, 25.70, 33.68, 35.24, 58.28, and 61.18°, which are assigned to the (003), (006), (012), (015), (110), and (113) crystalline planes, respectively. The observed peaks agree with the characteristic XRD pattern of lamellar structure and stacking planes inherent to the layered double hydroxide configuration . The XRD pattern of the Ce–CuFe catalyst indicated that Ce was successfully incorporated into the crystalline lattice of the layered catalyst.…”

“…These stacking planes indexed to the hexagonal lattice of the rhombohedral 3R system (R3m) authenticate the successful formation of LDH. 32 A slight shift is observed in the position of the (003) reflection as the intercalated anions are changed from CO 3 2− (11.95°) to SO 4 2− (11.98°) or Cl − (11.68°). 33,34 The changes observed with variation in the interlamellar anions can be correlated to the size and charge effects of the anions present in the gallery region and approve the successful anion exchange process.…”

Despite their diverse application profile, aromatic organochlorides such as 2,4,6-trichlorophenol (TP) are widely renowned for creating a negative toll on the balance of the ecosystem. Strict regulatory regimes are required to limit exposure to such organic pollutants. By deployment of a straightforward detection scheme, electrochemical sensing technology offers a competitive edge over the other techniques and practices available for pollutant monitoring.Here, we present a streamlined hydrothermal approach for synthesizing copper−manganese layered double hydroxide (CuMn-LDH) rods to be employed as electrocatalysts for detecting TP in various media. With a focused intention to leverage the full potential of the prepared CuMn-LDHs, the interlamellar region is configured using a series of intercalants. Further, a thorough comparative analysis of their structures, morphologies, and electrochemical performance is accomplished using various analytical techniques. The electrocatalytic oxidation ability of the CuMn-LDH toward TP molecules is markedly altered by incorporating various anions into the gallery region. The dynamic attributes of the developed sensor, such as a wide linear response (0.02−289.2 μM), a low detection limit (0.0026 μM), and good anti-interfering ability, acclaim its superior viability for real-time detection of TP with exceptional tolerance to the presence of foreign moieties. Hence, this work manifests that the nature of intercalants is a vital aspect to consider while designing LDH-based electrochemical probes to detect priority pollutants.

While shapes and surface properties of nanomaterials are known to play important roles in defining their properties, it remains challenging to finetune the morphologies systematically and predictably. Considering the extraordinary performance, prussian blue nanoparticles (PBNPs) are selected as the proof-of-concept nanomaterials. Herein, a DNA-dependence approach to fine-control the morphology of PBNPs via electrostatic interaction-mediated self-assembly of inorganic ions and protonated DNA is developed. The regulation of different DNA on the morphology of PBNPs is systematically investigated. 30-mer Oligo-C or -T (C30/T30) mediates formation of flowerlike PBNPs (PB nanoflowers), whereas cubic structure with different sizes is observed in the presence of 10-mer oligo-G or 30-mer Oligo-A (G10/A30). Detailed mechanism studies indicate that the protonation of nucleobases is the key factor for the morphological evolution. C30-dependent PB nanoflowers are superior to PB nanocubes in photothermal properties, peroxidase mimetic activity, photo-Fenton catalytic performance, and light scattering property, which present 1.2-, 3.78-, 1.58-, 1.93-fold improvement, respectively. Furthermore, PB nanoflowers mediated by the diblock DNA (sDNA; comprising C30 and complementary strands of the target DNA) unexpectedly acquire biorecognition capabilities. This study opens a new avenue for the systematic and predictable synthesis of PB nanoflowers, which broadens the repertoire of PBNPs for catalysis, biosensing, and imaging.
