摘要

A new 2D MOF with unique [Co-5(mu(3)-OH)(2)](8+) subunit, [Co-5(mu(3)-OH)(2)(bcpt)(4)(bib)(2)] (1) (H(2)bcpt = 3,5-bis(3'-carboxyphenyl)-1,2,4-triazole, bib = 1,4-bis(1-imidazoly)benzene) is prepared, which not only shows weak antiferromagnetic interaction between the adjacent Co(II) ion, but also exhibits efficient electrocatalytic hydrogen evolution reaction by the integration with graphene (Gr).
