Direct conversion of methane to formaldehyde and CO on B2O3 catalysts

open access: yesNature Communications, 2020
Partial oxidation of methane to value-added C1 products remains challenging due to the favorable formation of fully-oxidized CO2. Here, the authors show supported B2O3 catalysts with tri-coordinated BO3 units as the active site are highly selective in ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Fischer-tropsch synthesis on iron-based catalysts: the effect of co-feeding small oxygenates [PDF]

open access: yes, 1989
Co-feeding experiments have shown that ethers can participate substantially in the Fischer-Tropsch synthesis with iron catalysts. Dimethyl ether is thought to be capable of building up surface complexes which are very similar to those naturally occurring

Selective Benzene Capture by Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.
