Leng, Wancong; Cui, Leilei; Liu, Yang; Gong, Yun published the article 《MOF-Derived MnV2O4/C Microparticles with Graphene Coating Anchored on Graphite Sheets: Oxygen Defect Engaged High Performance Aqueous Zinc-Ion Battery》. Keywords: metal organic framework manganese vanadium oxide zinc ion battery.They researched the compound: 1,10-Phenanthroline( cas:66-71-7 ).SDS of cas: 66-71-7. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:66-71-7) here.
By annealing [Mn(phen)H2O][V2O6] (phen = 1,10-phenanthroline) in the presence of graphite template, MnV2O4 /C microparticles are obtained, in which MnV2O4 particles with one-layer or few-layer coating of graphene are anchored on the graphite sheets. The optimal sample, MnV2O4(p)/C-700 with a high carbon content (35.3 at %) can deliver a large specific capacity of 410 mAh g-1 at 0.1 A g-1 with a high capacity retention of 94.3 % over 1000 discharge/charge cycles at 20 A g-1 as cathode in zinc-ion battery. Ex situ X-ray diffraction, SEM, energy-dispersive X-ray spectra, as well as elemental mappings and XPS of MnV2O4(p)/C-700 discern the partial phase transformation mechanism of MnV2O4→Zn3(OH)2V2O7(H2O)2 during discharge/charge process. It is because the rich oxygen defects of MnV2O4 can improve elec. conductivity, favor the electron transfer from V→Mn/O, thus facilitate the binding of Zn2+, and the captured Zn2+ cannot be extracted, as evidenced by d. functional theory calculations Furthermore, it is found that O-deficiency can capture the water shell from the hydrated Zn2+, then the dehydrated Zn2+ is easy to insert into MnV2O4 with lower migration barrier of Zn2+ (0.84 eV), leading to the structural reversibility of MnV2O4 in cycling test.
This literature about this compound(66-71-7)SDS of cas: 66-71-7has given us a lot of inspiration, and I hope that the research on this compound(1,10-Phenanthroline) can be further advanced. Maybe we can get more compounds in a similar way.
