Tuning electrode surfaces to optimize solar fuel production

Green Car Congress

Scientists have demonstrated that modifying the topmost layer of atoms on the surface of electrodes can have a remarkable impact on the activity of solar water splitting. This photocurrent drives the chemical reactions that split water into oxygen and hydrogen. Choi and Galli, experimental and theoretical leaders in the field of solar fuels, respectively, have been collaborating for several years to design and optimize photoelectrodes for producing solar fuels.

ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

However, lithium is sourced almost exclusively from other countries, either concentrated using a solar evaporation process from natural brine sources or recovered from ore. The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium. The technique is very sensitive to hydrogen atoms, making it ideal for studying water.
