In situ hierarchical encapsulation of bimetallic selenides into honeycomb-like nitrogen doped porous carbon nanosheets for highly sensitive and selective guanosine detection

Recent research progress of selenotungstate-based biomolecular sensing materials

“…The effective enhancement of conductivity and electron-transfer ability of POM-based functional materials, to some degree, promotes the development of highly sensitive ECBs. 63,64 Motivated by these considerations, Zhao and colleagues rationally designed a novel P III -Se 2a). 65 In its polyoxoanion structure, two trivacant Keggin [SeW 9 O 33 ] 8− building units and a unique P III -Se IV -heteroatomdirecting trivacant Dawson [HPSeW 15 O 54 ] 10− building unit are integrated by a hexanuclear [Ce 2 (H 2 O)(W 4 O 9 )] 12+ heterometallic cluster.…”

Hierarchical Heterometallic Sulfur/Selenide Electrocatalysts Derived from Polyoxometalate for Enhanced Hydrogen Production Performance

“…This is mainly attributed to Se's bigger ionic radius as well as its low electronegativity. 23 Moreover, compared to simple bimetallic sulfides, the introduction of selenides further enhances the sustained stability of the material. 24 Polyoxometalates (POMs) constitute a wide-ranging category of inorganic clusters featuring metallic atoms and oxygen, characterized by diverse nanoscale dimensions and abundant structural variations.…”

“…In this context, selenium (Se) has demonstrated significant advantages as an element owing to its exceptional electronic conductivity, robust redox capabilities, enhanced affinity for transition-metal materials, abundant electroactive unsaturated edge sites, reduced band gaps, increased polarizability, and larger atomic size. This is mainly attributed to Se’s bigger ionic radius as well as its low electronegativity . Moreover, compared to simple bimetallic sulfides, the introduction of selenides further enhances the sustained stability of the material …”

Multifunctional metal selenide-based materials synthesized via a one-pot solvothermal approach for electrochemical energy storage and conversion applications

“…Dual ironnickel selenide (FeNiSe) materials are considered an adaptable path for combining new functions, such as electrochemical performance and electronic arrangement, in synergetic combination as active materials for SCs/OER/HER with improved redox reactions, easy assembly, and environmental friendliness. [26][27][28][29][30][31] Furthermore, to attain a higher energy density without sacrificing power density or cycling stability, structural characteristics must be fine-tuned by constructing nanostructures with more easily available active portions, large surface area, and porous morphologies. 32 The determination of the active center in FeNiSe is an area of ongoing research and scientific debate.…”
