MOF catalysts in biomass upgrading towards value-added fine chemicals
The development of new synthetic routes from biomass sources towards already existing molecules, which are then called bio-based molecules, or the transformation of biomass into new building blocks and materials will be of great impact. This review presents a critical comparison between MOFs and other catalysts (e.g. zeolites) for biomass transformation.
Solution-based sequential modification of LiCoO2 particle surfaces with iron(II) oxalate nanolayers
Facile creation of hybrid metal oxide-core/MOF-shell structures is achieved by stepwise solution-based modification of the core surface with a framework compound.
Acid–base directed supramolecular isomers of isophthalate based MOFs for CO2 adsorption and transformation
Directing supramolecular isomers using an acid versus a base, two MOFs with the same composition yet different topologies show differences in their catalytic efficacy to transform CO2 and epoxides into cyclic carbonates.
