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.
