Summary: In this study, a radical transformation that enables intramolecular oxygen atom transfer to alkenes using the nitro functionality in nitroarenes as an oxygen donor is disclosed. The reaction proceeds via iron-catalyzed metal hydrogen atom transfer to alkenes and subsequent oxygenation, resulting in alkene hydration. Compared to intermolecular radical oxygenation, the intramolecular variant offers advantages, particularly in terms of diastereoselective radical hydration of conformationally flexible alkenes. The aryl moiety connecting the reactive NO2-functionality to the alkene substrate can be cleaved after oxygen transfer, yielding products derived from a formal diastereoselective intermolecular alkene hydration. Additionally, the resulting aniline entity after oxygen transfer can be used for the construction of nitrogen-containing heterocycles.

Summary: This research explores CO2 valorization through hydrogenation using non-noble metals (Ni and Cu) supported on graphitic carbon nitride (g-C3N4). The catalysts exhibit stable activity and good conversions. Increasing the operating temperature during CO2 hydrogenation leads to higher CO2 conversion and selectivity for CO, while decreasing selectivity for methanol. The study also highlights the potential of g-C3N4 as a support material for atom-economy-designed catalysts.

Summary: In this article, a simple ex situ Sn-doping method on hematite nanoflakes (coded as MSnO2-H) is reported, which can protect the nanoflake morphology against high-temperature annealing and activate the photoresponse of hematite up to 800 nm wavelength. SnO2 nanoparticles synthesized on hematite nanoflakes effectively prevent shape deformation and enable heavy Sn ion doping. Moreover, SnO2 nanoparticles act as a passivation layer, reducing the onset potential of hematite for water splitting reactions.

Summary: Anchoring single metal atoms on suitable substrates is a convenient route towards materials with unique electronic and magnetic properties. Cyanographene (GCN), a highly functionalized graphene containing nitrile groups, offers a favorable arrangement for anchoring metal atoms. In this study, density functional theory (DFT) calculations were used to analyze the coordination effects in the binding of late 3d cations to GCN in aqueous solutions. Copper cations were found to be the most tightly bonded to GCN. Coordination effects significantly reduced the binding affinities predicted by implicit solvation models.

Summary: The investigation of photocatalytic systems at the nanoscale is crucial for understanding their fundamental principles, improving their design, and enhancing their applicability. A photochemical nanoscopy technique has been developed to detect the molecular products of plasmonic hot-carrier-driven photocatalytic reactions with nanometric precision. Applying this methodology to Au/TiO2 plasmonic photocatalysts, it was discovered that smaller and denser Au nanoparticle arrays have lower optical contribution but higher quantum efficiency in hot-hole-driven photocatalysis, which is closely related to population heterogeneity. This study also revealed the areas of oxidation and reduction product evolution in a single plasmonic nanodiode, demonstrating the bipolar behavior of such nanosystems. These findings enable quantitative investigations at the nanoscale to evaluate the photocatalytic reactivity of low-dimensional materials in various chemical reactions.
