Abstract: A solar fuels generator includes an anolyte and a catholyte in contact with a separator. The separator is configured such that the pH of the anolyte and the pH of the catholyte are each held at a steady state pH level during operation of the solar fuels generator. The steady state pH level of the anolyte is different from the steady state pH level of the catholyte.

Abstract: An Oxygen Evolution Reaction (OER) catalyst includes a metal oxide that includes oxygen, cerium, and one or more second metals. In some instances, the cerium is 10 to 80 molar % of the metals in the metal oxide and/or the catalyst includes two or more second metals. The OER catalyst can be included in or on an electrode. The electrode can be arranged in an oxygen evolution system such that the Oxygen Evolution Reaction occurs at the electrode.

Abstract: Carbon dioxide reduction includes bonding CO2 with an activator so as to form an activated intermediate. An electrical potential is applied to the intermediate so as to cause reduction of the CO2 in the intermediate. The CO2 reduction generates an organic fuel and releases the activator from the intermediate. The use of the intermediate suppresses H+ reduction reactions that compete with generation of the desired fuel.
