The article conveys some information:
The rational design and synthesis of mesoporous functional materials is of great significance to tackle fundamental challenges in materials science and to yield practical solutions for efficient energy utilization. Here, a novel p-toluenesulfonic acid-assisted mechanochem. approach is used to prepare a silica-templated bipyridine-containing covalent organic framework (COF), which can be further converted into an iron-nitrogen-doped mesoporous carbon (mC-TpBpy-Fe) upon carbonization and template removal. The resulting mC-TpBpy-Fe exhibits a large pore volume and surface area, which significantly promote the mass transfer efficiency and increase the accessibility of the active sites, yielding a high ORR activity with a competitive half-wave potential of 0.845 V and limiting c.d. of 5.92 mA/cm2 (vs 0.852 V and 5.57 mA/cm2 for Pt/C). Application of this COF derived mesoporous carbon within a Zn-air battery revealed that it can operate in ambient conditions with a competitive discharge performance, showing its potential for practical applications.

2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4) is a member of phloroglucinol derivatives. Phloroglucinol derivatives are a major class of secondary metabolites. Phloroglucinol compounds can be classified into monomeric, dimeric, trimeric and higher phloroglucinols, and phlorotannins.Recommanded Product: 34374-88-4
