Development of molecular electrocatalysts for hydrogen production and carbon dioxide reduction

Research output: Contribution to journalConference article

Abstract

Catalysts capable of efficient conversion between electrical energy and fuels will be important for a flexible and sustainable energy supply in the future. In recent work we have developed molecular electrocatalysts containing Ni, Co, or Fe for hydrogen oxidation and production and palladium complexes for CO 2 reduction to CO. The development of these catalysts is guided by an understanding of the contributions of both the first and second coordination spheres of these catalysts. Pendant bases incorporated in the second coordination sphere of the molecular catalysts for H 2 production and oxidation serve as proton relays controlling the movement of protons between the metal and acids or bases in solution. Insights into additional roles played by the pendant bases during the catalytic cycles will be discussed. Similarly, pendant Lewis or Bronsted acids in the second coordination sphere can assist in the electrocatalytic reduction of CO 2 to CO.
