Space-Confined Nucleation of Semimetal-Oxo Clusters within a [H₇P₈W₄₈O₁₈₄]^33– Macrocycle: Synthesis, Structure, and Enhanced Proton Conductivity

From confined growth to enhanced peroxidase-like activity: Nucleation of a phosphate-mediated Fe III–Ce III–oxo cluster inside the {P 8W 48} nanoreactor

“…Attempts to directly synthesize KLi-1 using, for instance, FeCl 3 •6H 2 O and Ce(NO 3 ) 3 •6H 2 O resulted in relatively low yields, suggesting the beneficial role of metal ion redox reactions in synthesis. A highly concentrated Li + -containing medium favored KLi-P 8 W 48 precursor activation through a cation-exchange process (K + → Li + ), which has been widely adopted in previous studies [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. Furthermore, KLi-1 crystallization was observed within the pH range of 3.5-5.5, and maximum yield achieved at pH = 5.0.…”

“…Through contributions primarily from research groups led by Kortz [25][26][27], Müller [26,28,29], Cronin [30][31][32], and Suzuki [33,34], {P 8 W 48 } has demonstrated the capability to host up to 22 elements across the periodic table, including d-, f-, and p-block metals of varying charges and radii [35][36][37][38][39][40]. Recent studies by Yang ) within {P 8 W 48 } [41][42][43], achieving unexpected outcomes such as the assembly of rare polyarsenate(III) under such confined microenvironments [43]. Motivated by these achievements, our study investigated whether metallic cations and nonmetallic oxyanions could be simultaneously accommodated by {P 8 W 48 }, including the implantation of heterometallic 3d-4f aggregates instead of 3d or 4f metals separately.…”

A review of metal–organic framework (MOF) materials as an effective photocatalyst for degradation of organic pollutants

“…Polyoxometalates (POMs), a subclass of polyoxoanions, primarily consist of very early transition metal ions, namely Mo and W. They were initially discovered in the late 19th century, but it is in recent decades that their prominence has grown due to the utilization of modern experimental techniques to investigate their exact structure. 197,198 POMs are widely accepted for their versatile applications as metal oxide or clusters. 199 Apart from having various structural features, the POMs possess brilliant physiochemical properties that make them ideal candidates for various applications, including magnetism, energy storage, photo, and electrocatalysis.…”

An Unusual Crystalline Porous Framework Constructed from Multitypes of Cages with Proton Conduction Property and Heterogeneous Catalytic Activity for Pyrazole Synthesis

“…Polyoxometalates (POMs), with their diverse shapes, sizes, charges, and metallic compositions, have emerged as promising materials in various research fields, including catalysis, materials science, pharmaceuticals, analytical chemistry, electrochemistry, and magnetism. − The attention from the research community has been particularly drawn to the different structural configurations and stacking modes of POMs, encompassing POM cages, , POM macrocycles, , inorganic and organic framework-based POMs, − POM organic polyhedra, and solid composite nanoclusters based on POMs . Among these, the cage structures, due to their beautiful structural features and captivating pore architectures, have been extensively investigated .…”
