Polyoxotungstate intercalated self-assembled nanohybrids of Zn-Cr-LDH for room temperature Cl2 sensing

Microwave-assisted hydrothermal fabrication of hierarchical-stacked mesoporous decavanadate-intercalated ZnAl nanolayered double hydroxide to exterminate different developmental stages of Trichinella spiralis and Schistosoma mansoni in-vitro

“…As visualized in Fig. 2 a, the parent ZnAl-LDH-NO 3 sample exhibits two distinct peaks at binding energies of 1046.3 eV and 1022.7 eV that arise from the spin-orbit splitting into Zn 2p 1/2 and Zn 2p 3/2 components, respectively [ 21 , 79 ]. The binding energy characteristic to Al element in ZnAl-LDH-NO 3 sample appears as a broad peak ( Fig.…”

Application of Polyoxometalates in Chemiresistive Gas Sensors: A Review

“…Shinde et al prepared mesoporous-layered nanohybrid materials of zinc chromium layered double hydroxide (Zn−Cr−LDH) and polyoxytungstate (POW) anions. 42 The Cl 2 gas response of the original Zn−Cr−LDH was 25.2%, and the gas response to Cl 2 after hybridization with POW anions was increased to 66.8%. On this basis, in the same year, the research group prepared high mesoporous ZCiV nanohybrids by lattice engineering self-assembly between cationic Zn−Cr−LDH nanosheets and anionic POM isopolyvanadate (iPOV) nanoclusters (Figure 13).…”

“…Bezdek et al provided the SWCNT-P4VP-Pt-POM composite by immersing the device in DMSO mixed with POM [H 5 PV2Mo 10 O 40 ] for 18 h at room temperature to achieve anion exchange, thereby providing the SWCNT-P4VP-Pt-POM composite. , For complex mesoporous materials, Ren et al explored an unusual block copolymers-directed orthogonal assembly method through the co-assembly of amphiphilic diblock copolymers and POMs and subsequent calcination-induced structural transformation and conveniently constructed three-dimensional multilayer-crossed metal-oxide semiconductor nanowire arrays . Shinde et al prepared highly mesoporous nanohybrids by lattice engineering self-assembly of two-dimensional cationic Zn–Cr–LDH nanosheets and polyoxotungstate. , …”

3D architectured zinc–chromium layered double hydroxide with nickel cobalt sulfide composite for the electrochemical detection of ronidazole

“…[24][25][26] LDHs possess brucite-type structures that result in a unique shape, and they are non-toxic with a tunable cation structure, anion exchange capacity at the interlayers, huge surface area, increased stability, and satisfactory flexibility. [27][28][29][30] In recent times, transition metal-based LDHs have functioned as excellent electrocatalysts in sensing applications. 31,32 Herein, we synthesized zinc-chromium-LDH (ZC), which is an n-type semiconductor material that acquires many redox sites with satisfactory catalytic activity and employed as an electrocatalyst.…”
