Abstract:
Using the mixed‐metal approach, a direct synthesis route at ambient pressure was developed for a new type of bimetallic metal‐organic framework based on the CPO‐27 structure. The structural characterization of CPO‐27(Cu 0.6 −CS−Co 0.4 ) using X‐ray diffraction, transmission electron microscopy, energy‐dispersive X‐ray mapping and X‐ray absorption spectroscopy revealed that the Cu 2+ and Co 2+ ions were exclusively incorporated at the metal positions of the CPO‐27 lattice, but with a core‐shell distribution within the crystallites. The parent framework material was then utilized as a precursor for the generation of novel bimetallic carbon‐supported materials using the controlled thermal decomposition in a reducing atmosphere. During this decomposition process, the distribution of the two metals remained the same, which resulted in unique needle‐shaped particles with a high dispersion of cobalt at the periphery of the amorphous carbon and agglomerated copper particles in the inside.
