Recent investigations reveal that by providing active sites for O–O bond formation, Fe(III) oxyhydroxides (FeOOH) dramatically enhance the oxygen evolution activities of iron-containing abundant-earth CoOxHy and NiOxHy electrocatalysts. In contrast to α-Fe2O3 (hematite), however, little detailed information is available concerning fundamental reactivities themselves. We here report a macroanion-like polyoxometalate cluster-anion complex 2.6 nm γ-FeOOH nanocrystals, 1, not only catalyzes...
Dissolution of the polyoxometalate (POM) cluster anion H5[PV2Mo10O40] (1; a mixture positional isomers) in 50% aq H2SO4 dramatically enhances its ability to oxidize methylarenes, while fully retaining high selectivities typical this versatile oxidant. To better understand impressive reactivity, we now provide new information regarding nature 1 (115 mM) (9.4 M) H2SO4. Data from 51V NMR spectroscopy and cyclic voltammetry reveal that as volume water is incrementally increased 50%, V(V) ions...
Both natural enzymatic systems and synthetic porous material catalysts utilize well-defined uniform channels to dictate reaction selectivities on the basis of size or shape. Mimicry this design element in homogeneous is generally difficult owing flexibility inherent most small molecular species. Herein, we report synthesis a tripodal ligand scaffold that orients narrow rigid cavity atop accessible metal coordination space. The permanent void formed through macrocyclization whereby...
The formation of small 1 to 3 nm organic-ligand free metal-oxide nanocrystals (NCs) is essential utilization their attractive size-dependent properties in electronic devices and catalysis. We now report that hexaniobate cluster-anions, [Nb6 O19 ]8- , can arrest the growth NCs stabilize them as water-soluble complexes. This exemplified by hexaniobate-complexed 2.4-nm monoclinic-phase CuO (1), whose ca. 350 Cu-atom cores feature quantum-confinement effects impart an unprecedented ability...
The selective uptake of guests by capsules, cages, and containers, porous solid-state materials such as zeolites metal–organic frameworks (MOFs), is generally controlled pore size the dimensions chemical properties interior host domains. For soluble structures, however, few options are available for modifying their outer pores to impart chemoselectivity similarly sized guests. We now show that using alkane-coated gold cores structural building units (SBUs) hydrophobic self-assembly...
Porous organic cages (POCs) and metal-organic polyhedra (MOPs) function as zero-dimensional porous materials, able to mimic many functions of insoluble framework materials while offering processability advantages. A popular approach access tailored metal-based motifs in extended network is postsynthetic metalation, which allows metal installation be decoupled from assembly. Surprisingly, this has only sparingly been reported for molecular materials. In report, we demonstrate metalation...
Abstract The formation of small 1 to 3 nm organic‐ligand free metal‐oxide nanocrystals (NCs) is essential utilization their attractive size‐dependent properties in electronic devices and catalysis. We now report that hexaniobate cluster‐anions, [Nb 6 O 19 ] 8− , can arrest the growth NCs stabilize them as water‐soluble complexes. This exemplified by hexaniobate‐complexed 2.4‐nm monoclinic‐phase CuO ( ), whose ca. 350 Cu‐atom cores feature quantum‐confinement effects impart an unprecedented...

Water oxidation is a multielectron complex reaction that produces molecular oxygen as the final product. The article addresses lack of confirmation product formation in electrochemical evolution (OER) studies, despite extensive research conducted on catalysts for water splitting. It critically evaluates trend observed many studies solely rely methods OER quantification without confirming via complementary analytical techniques. omission measuring evolved gas leaves crucial gap process and...
