The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II)( cas:28903-71-1 ) is researched.Synthetic Route of C48H38CoN4O4.Ma, Wenjie; Wu, Fei; Yu, Ping; Mao, Lanqun published the article 《Carbon support tuned electrocatalytic activity of a single-site metal-organic framework toward the oxygen reduction reaction》 about this compound( cas:28903-71-1 ) in Chemical Science. Keywords: carbon metal organic framework electrocatalytic activity oxygen reduction reaction. Let’s learn more about this compound (cas:28903-71-1).
Metal-organic frameworks (MOFs) possess fantastic features such as structural diversity, tunable accessible pores and atomically dispersed active sites, holding tremendous potential as highly versatile platforms for fabricating single-site catalysts. The electrocatalytic activity of single-site MOFs can be improved and tuned via several approaches; however, the exploitation of different carbon supports to modulate the nature of single active sites in MOFs for electrocatalysis has not been reported. Here, we find that the electrocatalytic activity of single-site MOFs toward the oxygen reduction reaction (ORR) can be tuned by using carbon nanomaterials, i.e., carbon nanotubes and graphene, as supports through MOF-support interactions in the manner of geometric and electronic effects. The introduction of MOF-support interactions not only greatly improves the electrocatalytic performance of MOFs toward the ORR in terms of onset and half-wave potentials and c.d., but also alters the reaction pathway of the ORR. This finding provides a new horizon for the design and synthesis of single-site MOFs for electrocatalysis.
