Abstract
This project proposes a bio-inspired synthesis route of dissipative materials, created in conditions away from the thermodynamic equilibrium, as paradigmatic catalysts for the production of dense energy carriers from the electrochemical reduction of carbon dioxide. The materials will be synthesized at the solid/liquid interface by nonlinear electrodeposition reactions, aiming at a higher level of complexity and emerging properties which are not obtained by usual synthetic methods. Emphasis will be given to the design and control of a microscale segregated phase structure, between copper and gold, silver or zinc, for example, in order to induce a catalytic reaction in tandem (or cascade). In this strategy, carbon monoxide will be produced in the guest metal and sequentially dimerized at active copper sites, forming molecules with multiple carbon atoms. The electronic and structural properties of the dissipative material will be evaluated by X-ray spectroscopies and advanced microscopy techniques, being intrinsically correlated with product distribution. It is expected to create new catalysts, with easy scaling up, that surpass the state-of-the-art benchmarks for electrochemical reduction of carbon dioxide. (AU)
