Graphitic phosphorus coordinated single Fe atoms for hydrogenative transformations

open access: yesNature Communications, 2020
Phosphorus ligands have been extensively used in metal complexes for homogeneous catalysis. Here, the authors broaden this scope to heterogeneous catalysis by preparing a P-coordinated Fe single atom catalyst with excellent catalytic performance in ...

Metal-organic frameworks as selective or chiral oxidation catalysts [PDF]

open access: yes, 2014
Since the discovery of Metal Organic Frameworks (MOFs) in the early 1990s, the amount of new structures has grown exponentially. A MOF typically consists of inorganic nodes that are connected by organic linkers to form crystalline, highly porous ...
