| Popis: | Efficient electrocatalytic production of H2 from mixed water/acetonitrile solutions was achieved using three new CoII complexes supported by the neutral pincer ligand bis(diphenylphosphino)-2,6-di(methylamino)pyridine ("PN3 P"). At -1.9 V vs. Fc/Fc+ , these catalysts showed 96 % Faradaic efficiency with added water or saturated aqueous saline at rates of up to 316 L(mol cat)-1 (cm2 )-1 h-1 using a glassy carbon working electrode. The complex [Co(κ3 -2,6-{Ph2 PNMe}2 (NC5 H3 )Br2 ] (1) was also able to photocatalytically reduce water to hydrogen in the presence of a Ru(bpy)32+ photosensitizer and a reductant. |
