Systems and methods for the electrochemical conversion of COT to multi-carbon products are provided. Each system and method comprises a sequence of multiple, independently optimized electrochemical reaction steps that take place in separate reaction chambers.

Multi-step process and system for converting carbon dioxide to multi-carbon products

Electrocatalysts of formula A,BO, wherein A=a metal with an acid-stable oxide and B=a platinum-group-metal (PGM), are provided, as are methods of making the electrocatalysts via rapid plasma oxidation, methods of using the electrocatalysts to catalyze e.g. oxygen evolution reactions (OERs), and devices comprising the electrocatalysts.

Electrocatalytic materials for oxygen evolution of formula ABO

Some embodiments of the invention include methods of using a compound (e.g., Formula (I)) for the reduction of carbon dioxide to formate by contacting the carbon dioxide with a composition comprising a compound. In certain embodiments, the source of the carbon dioxide is air or is flue gas. Additional embodiments of the invention are also discussed herein.

Methods for the reduction of carbon dioxide

Hydrogen gas as a power source is obtained from gaseous water, including seawater vapor existing abundantly at near-surface levels of the oceans or humid air over land. An integrated system of photovoltaic cells for capturing and harnessing solar energy is combined with a water vapor electrolysis system comprising an electrolyzer with an anode compartment and a cathode compartment separated by a proton exchange membrane. The photovoltaic aspects of the system convert the energy of the sun to drive electrolysis of gaseous water from the environment. The electrolyzer aspects include an anode, a cathode, and a proton exchange membrane. At the anode, oxygen evolution reaction (OER) catalysts oxidize HO to oxygen gas and protons, the latter being diffused through a membrane (e.g., a solid polymer electrolyte membrane such as Nafion). At the cathode, photogenerated electrons are conducted to hydrogen evolution reaction (HER) catalysts to reduce the protons to hydrogen gas, while concentration gradients drive the generated Oback to the atmosphere.
