A catalyst composition comprising at least a catalyst compound selected from multi metal cyanide compounds for the selective production of oxazolidinone compounds by reacting an isocyanate compound with an epoxide compound and oxazolidinone comprising materials obtained using said catalyst compound.

Prussian blue analog derived catalysts having a composition of highly porous transition metal (TM) oxides with nano particle size. Such OER catalysts are synthesized from the PBA, containing cobalt, iron, nickel, copper, manganese, zinc, magnesium etc., as secondary building units (SBUs) coordinated by hexacyano-based ligands. Furthermore, the PBA-derived catalysts may also integrated into a highly graphitized carbon network to further improve the conductivity, mass transport and durability against oxidative corrosion.
