摘要：Two novel water stable metal-organic frameworks, [Cu(L)·(4,4′-bipy)·(ClO4)]n(1), [Cu(L)·(phen)·(ClO4)·(H2O)]2(2), have been constructed by HL=[5-Mercapto-1-methyl] tetrazole acetic acid and Cu (II) salt in the presence of assistant N-containing ligands. MOF1and MOF2with open CuIIsites, resulting the framework1and2show electrocatalytic activity for water oxidation in alkaline solution. The electrochemical properties of complex for oxygen evolution reaction (OER) were evaluated by linear sweep voltammetry (LSV) and the Tafel slopes. Complex1has a higher LSV activity with a lower over potential of 1.54 V and a much higher increase in current density. Meanwhile, the Tafel slope of complex1(122.0 mV dec-1) is much lower than complex2(243.5 mV dec-1). This phenomenon makes complex1a promising porous material for electrocatalytic activity.
