Abstract
- Four Ni, Co, Cu, Zn-containing coordination polymers incorporating 4,4′,4′′,4′′′-tetrakiscarboxyphenylsilane (H<subscript>4</subscript>tcps) and 1,3,5-tris(2-methyl-1H-imidazol-1-yl)benzene (tmib) ligands, namely [Ni<subscript>6</subscript>(tcps)<subscript>3</subscript>(tmib)<subscript>4</subscript>(H<subscript>2</subscript>O)<subscript>2</subscript>] (1), [Co<subscript>6</subscript>(tcps)<subscript>3</subscript>(tmib)<subscript>4</subscript>] (2), [Cu<subscript>2</subscript>(tcps)(tmib)(H<subscript>2</subscript>O)] (3) and [Zn<subscript>2</subscript>(tcps)(tmib)] (4), were synthesized by the solvothermal method. Compounds 1 and 2 were isostructural with three-dimensional (3D) (3,4)-connected frameworks. Compounds 3 and 4 possessed (3,4)-connected 3D networks with (6·8<superscript>2</superscript>)(6·8<superscript>5</superscript>)(6<superscript>2</superscript>·8<superscript>2</superscript>·10<superscript>2</superscript>)(6<superscript>2</superscript>·8) and (4·6·8)(4·6<superscript>3</superscript>·8<superscript>2</superscript>)(6<superscript>6</superscript>)(6<superscript>7</superscript>·8<superscript>3</superscript>) topology, respectively. The thermal derivatives of compounds 1 and 2, Co-800 and Ni-700, exhibited low OER overpotentials of 338 and 388 mV to achieve a current density of 10 mA cm<superscript>−2</superscript> and hold their electrocatalytic activity for at least 9 hours in 1 M KOH.
