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.

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.

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)

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.

Stanford team identifies root cause of lithium intrusion into solid electrolytes

Green Car Congress

Researchers at Stanford University and SLAC National Accelerator Laboratory now report that the root cause of lithium intrusion into the electrolyte is a combination of current focusing and the presence of nanoscale cracks, rather than electronic leakage or electrochemical reduction.
