The role of manganese in CoMnO_x catalysts for selective long-chain hydrocarbon production via Fischer-Tropsch synthesis

The molecular-level mechanism by which manganese enhances cobalt catalysts for Fischer−Tropsch synthesis (FTS) of long-chain hydrocarbons from syngas is not well understood. Here, the authors demonstrate that manganese promotes long-chain hydrocarbon production in Co-based FTS catalysts by binding H at basic O sites on MnO, reducing chain termination on Co and thus promoting C₅₊ products.

Engineering bright sub-10-nm upconverting nanocrystals for single-molecule imaging

Upconverting nanoparticles smaller than 10 nm are brighter when excited under single-particle conditions than when they are part of an ensemble.

Nanometre-resolved observation of electrochemical microenvironment formation at the nanoparticle–ligand interface

Nanoparticles are often stabilized by capping ligands but the specific role of such ligands during catalytic processes is often ignored. Now, in situ techniques including spatially resolved infrared nanospectroscopy reveal the ligand-assisted formation of a catalytic microenvironment on the surface of silver nanoparticles with nanoscale precision during CO₂ electroreduction.

Three-dimensional periodic supramolecular organic framework ion sponge in water and microcrystals

The construction of soluble periodic supramolecular three-dimensional networks is challenging. Here, the authors use an encapsulated dimerization strategy to direct the assembly of a periodic three-dimensional supramolecular organic framework and evaluate its absorption properties.

Facile transformation of imine covalent organic frameworks into ultrastable crystalline porous aromatic frameworks

Despite recent success in developing new covalent organic frameworks (COFs) materials, synthesis of chemically stable COFs still remains challenging. Here the authors demonstrate a facile strategy that transforms imine-linked COFs into robust porous aromatic frameworks by kinetically fixing the reversible imine linkage via an aza-Diels-Alder cycloaddition reaction.
