Summary: Although the oxidation of alcohols by metal nitrido complexes has not been studied extensively, this report demonstrates the visible-light-induced oxidation of primary and secondary alcohols to carbonyl compounds using a strongly luminescent osmium(VI) nitrido complex (OsN). The proposed mechanism involves the rate-limiting hydrogen-atom transfer from the alpha-carbon of the alcohol to OsN*. Attempts to catalytically oxidize alcohols by OsN* using PhIO as the terminal oxidant resulted in the formation of novel osmium(IV) iminato complexes where the nitrido ligand is bonded to a 6-carbon of the alcohol. Experimental and theoretical studies suggest that OsN* is reductively quenched by PhIO to generate highly active PhIO+ oxidant, which readily undergoes alpha- and 6- C-H activation of alcohols.

Summary: Versatile persulfate-based catalytic mechanisms induced by highly-effective single atom catalysts (SACs) have been intensively studied. However, the relationship between the different mechanisms and the properties of pollutants has been overlooked. In this study, the redox potential characteristics of eight selected pollutants were determined, and a correlation between their redox potentials and oxidation performances/pathways in the Mn-SAC/PMS system was confirmed. Based on these insights, the sources of Fenton-like systems with tunable oxidation processes can be revealed.

Summary: This paper analyzes the influence of Al distribution, zeolite topology, ligands/reagents, and oxidation state on ions mobility in Cu-zeolites, and its impact on the reactivity of metal sites. The mobility of Cu ions has been observed in the presence of ammonia, enabling the activation of oxygen and providing a new perspective on the chemistry of zeolite-based catalysts. The different mobility of Cu+/Cu2+ ions, even in the absence of ligands, has important implications for the formation of Cu-oxo species and their activity in relevant reactions.

Summary: Single-atom nanozymes (SAzymes), with twisted, nonplanar Fe-O3N2 active sites similar to the non-heme iron center of HppE, were successfully synthesized using carbon dots (CDs) as the support. The Fe-CDs exhibited excellent peroxidase (POD) activity, surpassing the values of conventional SAzymes with planar Fe-N-4. Furthermore, an activatable Fe-CDs-based therapeutic agent with near-infrared enhanced POD activity, photothermal effect, and tumor-targeting ability was developed. This research represents a significant advancement in the design of high-performance SAzymes and provides guidance for future applications in synergistic tumor therapy.

Summary: By anchoring single atom Pt on the surface of SiO2 using ionic liquid, it was found that Pt1(0.1 %)/SiO2 exhibited a significant catalytic effect in generating H2O2, with a concentration 25.2 times and 11.6 times higher than those from pure ultrasound and sonocatalytic processes of Ptn(0.1 %)/SiO2, respectively. This enhancement can be attributed to the dual catalytic processes of Pt1, including sono-splitting of H2O to generate center dot OH as the precursor of H2O2 formation, and the combination of O2 and center dot H to selectively generate center dot OOH.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
