Recent advances in polyoxometalate-based materials and their derivatives for electrocatalysis and energy storage

“…The polymer exhibits electrical conductivity primarily via the delocalized electrons in the main chain and utilizes the abundant functional groups or positive properties to support POMs by physical cross-linking and electrostatic interaction. 201,202 Liu et al 203 prepared PMo 12 /PPy composite via anchored PMo 12 onto a highly interconnected 3D conductive polypyrrole (PPy) hydrogel scaffold (Fig. 22a).…”

Alkoxy-Functionalized Hydroxamate/Zinc Metal–Organic Frameworks and the Effects of Substituents and Acid Addition on Their Structures

“…In the past two decades, metal–organic frameworks (MOFs), which are porous materials composed of metal ions and organic linkers, have been extensively developed for potential applications in gas storage, separation, and catalysts. − In particular, the separation of CO 2 from flue gas using porous materials seems to be promising due to their excellent CO 2 -separation properties. − Depending on the constituents and the reaction conditions, diverse structures have been reported for these MOFs. , Carboxylate ligands are widely used as coordination moieties in MOFs owing to their facile preparation and strong binding affinity for metal ions. Although the use of alternative ligands can be expected to provide MOFs with new structures, such studies are less common than those for carboxylates.…”

Orthogonal Postsynthetic Copolymerization of Hydrogen‐Bonded Organic Frameworks into a PolyHOF Membrane

“…Physical blending is the simplest method; however, leakage of HOF particles from the polymer matrix has been observed. [14] Conversely, covalent attachment is significantly more stable and can effectively avoid interfacial gaps as well as the inhomogeneous dispersion of HOFs in the polymeric matrix. [15] However, establishing covalent bonds between HOFs and polymers without compromising H-bonds and other functional sites demands meticulous design.…”
