Berkeley Lab nanoscale imaging study yields key insights into photo-electrochemical water splitting

Green Car Congress

In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel—just as plants do—researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. —Johanna Eichhorn.

New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. These free charges split water molecules into hydrogen and oxygen. … in neutral (pH?~?7.0)

Stanford team identifies root cause of lithium intrusion into solid electrolytes

Green Car Congress

Lithium metal batteries with solid electrolytes are lightweight, inflammable, pack a lot of energy, and can be recharged very quickly, but they have been slow to develop due to mysterious short circuiting and failure. Nat Energy doi: 10.1038/s41560-022-01186-4 Resources McConohy, G.,

PNNL study uncovers role of water in forming impurity in bio-oil upgrading; insight into fundamentals of biofuel catalysis

Green Car Congress

In working to elucidate the chemistry of hydrodeoxygenation (HDO) for the catalytic upgrading of pyrolytic bio-oil to fuel-grade products, researchers at Pacific Northwest National Laboratory (PNNL) have discovered that water in the conversion process helps form an impurity which, in turn, slows down key chemical reactions.

KAUST team alters atomic composition of MoS2 to boost performance as water-splitting catalyst for H2 production

Green Car Congress

Researchers at KAUST have developed and used a novel way of increasing the chemical reactivity of a two-dimensional molybdenum disulfide material to produce a cheap and effective catalyst for water splitting to produce hydrogen. A monolayer of molybdenum disulfide is only reactive for reducing water to hydrogen at its edge.

Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

Electrocatalysis and photocatalysis (artificial photosynthesis) are among the most promising ways to achieve effective storage for renewable energy. Knowing the exact structure of the activated CO 2 is essential because its structure dictates both the end product of the reaction and its energy cost.
