Bi-metallic [Cu/Co(6mna)2]n metal organic chalcogenolate frameworks as high-performance electro-catalysts for dye-sensitized solar cells: a ligand-assisted bottom-up synthesis

Superior electro-catalytic activity of a heterogeneous bi-metallic [Cu/Co(6mna) 2 ] n MOF was established by synergistic effects between conductive [Cu 2 (6mna)(6mn)NH 4 ] n with 2D (–Cu–S–) n planes and porous [Co 2 (6mna) 2 ] n with helical (–Co–S–) n chains.
