Energetics of carboxylate-metal bonds in polymetallic rings. [PDF]

Chem Commun (Camb)
Using collision-induced dissociation mass spectrometry and density functional theory, we assess the energetics of polymetallic [Cr7NiF8(O2CR)16]- anions in vacuo, showing how the carboxylate influences the ring stability. We find the best correlation with the enthalpic contribution to the computed proton affinity of the isolated carboxylates ...

Bioinspired trimesic acid anchored electrocatalysts with unique static and dynamic compatibility for enhanced water oxidation

Nature Communications, 2023
Layered double hydroxides are promising candidates for the electrocatalytic oxygen evolution reaction. Unfortunately, their catalytic kinetics and long-term stabilities are far from satisfactory compared to those of rare metals.

Electron-Induced Decomposition of Different Silver(I) Complexes: Implications for the Design of Precursors for Focused Electron Beam Induced Deposition

Nanomaterials, 2022
Focused electron beam induced deposition (FEBID) is a versatile tool to produce nanostructures through electron-induced decomposition of metal-containing precursor molecules. However, the metal content of the resulting materials is often low.

In situ grown oxygen-vacancy-rich copper oxide nanosheets on a copper foam electrode afford the selective oxidation of alcohols to value-added chemicals

Communications Chemistry, 2022
Converting low-molecular-weight aliphatic alcohols like methanol and ethanol into value-added chemicals such as carboxylates in electrolytic cells offers low operating costs, but non-noble-metal catalysts often bring about low selectivities and ...

Porous Metal Carboxylate Boron Imidazolate Frameworks [PDF]

Angewandte Chemie, 2010
Integrated Material for Efficient CO2 Storage A new family of porous materials with tunable gas sorption properties have been made by integrating metal carboxylates and boron imidazolates under hydro- or solvothermal conditions. One hydrothermally synthesized phase exhibits a very high volumetric CO2 storage capacity at 81 L/L (273K, 1atm).
