Abstract: The solar fuels generator includes an ionically conductive separator between a gaseous first phase and a second phase. A photoanode uses one or more components of the first phase to generate cations during operation of the solar fuels generator. A cation conduit is positioned provides a pathway along which the cations travel from the photoanode to the separator. The separator conducts the cations. A second solid cation conduit conducts the cations from the separator to a photocathode.

Abstract: Various samples are generated on a substrate. The samples each includes or consists of one or more analytes. In some instances, the samples are generated through the use of gels or through vapor deposition techniques. The samples are used in an instrument for screening large numbers of analytes by locating the samples between a working electrode and a counter electrode assembly. The instrument also includes one or more light sources for illuminating each of the samples. The instrument is configured to measure the photocurrent formed through a sample as a result of the illumination of the sample.

Abstract: Electrochemical experiments are performed on a collection of samples by suspending a drop of electrolyte solution between an electrochemical experiment probe and one of the samples that serves as a test sample. During the electrochemical experiment, the electrolyte solution is added to the drop and an output solution is removed from the drop. The probe and collection of samples can be moved relative to one another so the probe can be scanned across the samples.

Abstract: A solar fuels generation system includes a first reactor that contains a first solution in which a charge carrier is reduced to a reduced charge carrier. The system also includes a second reactor that contains a second solution in which the reduced charge carrier reduces protons so as to generate hydrogen gas.

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: 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.

Abstract: Systems and methods for electrochemical hydrogen looping cells are described. Generating a pH swing can expedite carbon dioxide capture from oceanwater. Many embodiments implement electrochemical hydrogen looping cells that simultaneously produce acid via anodic hydrogen oxidation and base via cathodic hydrogen evolution to generate a pH change.
