Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: PD2DBA3, is researched, Molecular C51H42O3Pd2, CAS is 60748-47-2, about A novel 2D Co3(HADQ)2 metal-organic framework as a highly active and stable electrocatalyst for acidic oxygen reduction.Reference of PD2DBA3.
Efficient and robust electrocatalysts for acidic Oxygen reduction reaction (ORR) is crucial for the proton exchange membrane hydrogen fuel cells. However, the current electrocatalysts suffer from the stability issues in the acidic environment during ORR. Herein, we introduce a new layer-stacked two-dimensional (2D) metal-organic framework (MOF), Co3(HADQ)2 (HADQ = 2,3,6,7,10,11-hexaamine dipyrazino quinoxaline), synthesized for the first time. This novel MOF material shows the extremely high conductivity of 8,385.744 S/m with extraordinary activity (E1/2 = 0.836 V vs. RHE, n = 3.93, and jL = 5.31 mAcm-2) and an exceptional stability (up to 20,000 cycles) as the electrocatalyst for ORR in an acidic media (pH = 0.29), outperforming most of the state of the art Metal-N-C and single-atom electrocatalysts for acidic ORR. D. functional theory calculations indicate that the Co-sites are the active sites. We propose that Co3(HADQ)2 is a promising model catalyst for mechanistic studies of acidic ORR, due to its well defined and tunable structure.
As far as I know, this compound(60748-47-2)Reference of PD2DBA3 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
