Synthesis and electro-catalytic properties of a dinuclear triazenido-palladium complex

Synthesis and studies of a molecular copper(I)-triazenido electrocatalyst for catalyzing hydrogen evolution from acetic acid and water

“…S2, the cyclic voltammogram of complex 1 exhibits three irreversible redox waves at À1. 22 couples, respectively. The current responses of the redox events at À1.22, À1.53 and À1.95 V show a linear dependence on the square root of the scan rate, which is indicative of a diffusion-controlled process, with the electrochemically active species freely diffusing in the solution.…”

“…It has been shown that the donor type and the electronic properties of the ligands play vital roles in determining the structure and reactivity of the corresponding metal complexes. With this in mind, our group has tried to probe new electro-catalysts through the synthesis of dinuclear complexes with triazenido ligands [21,22]. The central nitrogen of the triazenido ligand imparts greater basicity on [NÁ Á ÁNÁ Á ÁN] À relative to neutral nitrogen, making the triazenido more electron donating, amenable to binding to H + and hydrogen production.…”

A new molecular electro-catalyst based on a triazenido–cobalt complex for generating hydrogen from both acetic acid and water

“…Within this context, we have studied triazenido ligands and their corresponding complexes for catalytic applications, because the central nitrogen of the triazenido ligand imparts greater basicity on the [N⋯N⋯N] − relative to the neutral nitrogen, making the triazenido more electron donating, amenable to binding to H + and hydrogen production. Preliminary research suggests that copper, cobalt and palladium complexes supported by triazenido ligands can catalyze proton reduction, but the mechanism is not clear [19][20][21][22][23][24]. In this paper, we report the synthesis, structure and characterization of a new triazenido-cobalt complex [CoL 3 ] 1, as well as its electrocatalytic function for hydrogen evolution from acetic acid or water thereof.…”
