SDS of cas: 28903-71-1. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), is researched, Molecular C48H38CoN4O4, CAS is 28903-71-1, about ZIF-8 MOF Encapsulated Co-porphyrin, an Efficient Electrocatalyst for Water Oxidation in a Wide pH Range: Works Better at Neutral pH.
Water oxidation (WO) is the most important and thermodynamically challenging process associated with water splitting. Several metal porphyrins are reported to perform catalytic WO through the central metal but [5,10,15,20-tetrakis(4-methoxyphenyl)porphyrinato]cobalt(II) (abbreviated as CoTMPP), which is well-known for its ability to perform oxygen reduction reaction (ORR), lacks the capacity to perform WO. Here we have successfully activated CoTMPP towards electrochem. WO by means of its in situ encapsulation inside the cavity of a versatile metal organic framework (MOF), known as zeolitic imidazolate framework-8 (ZIF-8). The composite, thus prepared i. e., CoTMPP@ZIF-8 (abbreviated as CTMZ-8), behaves as a heterogeneous, robust, and efficient electrocatalyst for oxygen evolution reaction (OER) at a wide pH range (from acidic to neutral). Required overpotential (η) of 387.4 mV (neutral pH) and 562.7 mV (pH 2) and high turnover frequency (TOF) of 2.7 s-1 (at neutral pH) make this composite (CTMZ-8) an efficient electrocatalyst for WO. To the best of our knowledge, this is the first report of electrocatalytic WO by CoTMPP.
