Inversed Cation Size Effects on Methanol Formations From CO2 Electroreduction by Immobilized Cobalt Phthalocyanine

open access: yesAngewandte Chemie, Volume 138, Issue 27, 1 July 2026.
Multiscale simulations reveal an inversed cation size effect (Li+ > Na+ > K+ > Cs+) in immobilized cobalt phthalocyanine ‐catalyzed CO2 reduction to methanol. Smaller cations like Li+ effectively stabilize the rate‐limiting proton‐transfer transition state through intimate coordination, whereas their disruption of the local hydrogen‐bond network ...

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

open access: yesAdvanced Functional Materials, Volume 36, Issue 54, 6 July 2026.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.

129Xe Nuclear Magnetic Resonance Spectroscopy of Metal–Organic Frameworks

open access: yesAnalysis &Sensing, Volume 6, Issue 4, July 2026.
129Xe NMR spectroscopy is a powerful technique to study porous materials. Properties such as pore sizes, pore connectivity, and dynamic switching processes associated with adsorption can be investigated. With its inertness and highly polarizable electron cloud, Xe allows for sensitive monitoring of small changes in the surface chemistry of materials ...

Steric modulation of nitric oxide photodissociation kinetics in iron–nitrosyl complexes

open access: yesBulletin of the Korean Chemical Society, Volume 47, Issue 7, Page 772-776, July 2026.
Subtle steric modification within a pyridinophane ligand framework modulates nitric oxide photodissociation kinetics in iron–nitrosyl complexes. Structural and electrochemical analyses reveal that modest ligand‐environment variations are reflected in differences in NO photoreactivity.
