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)

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

Green Car Congress

Researchers at Columbia University have solved the first piece of the puzzle; they have proved that CO 2 electroreduction begins with one common intermediate, not two as was commonly thought. Their paper is published in Proceedings of the National Academy of Sciences (PNAS). 1802256115.

Researchers find two strains of diesel-eating bacteria in Antarctica

Green Car Congress

This insight could potentially inform bioremediation efforts in the region. But both strains were able to adapt to a wide range of temperatures, so could be deployed during summertime when temperatures are higher, soils are unfrozen, and water is more accessible. The results show that strain ADL36 is better at diesel biodegradation.

Nanobox strategy to improve performance of Li-S batteries

Green Car Congress

Researchers at Changchun University of Science and Technology in China have developed a nanobox strategy to improve the performance of lithium-sulfur batteries. The ZIF-67 nanocubes were dispersed in a mixed solution containing ethanol (20 mL) and deionized water (5 mL). A paper on their work appears in the Journal of Power Sources.

New solid polymer electrolyte outperforms Nafion; novel polymer folding

Green Car Congress

Researchers, led by a team from the University of Pennsylvania, have used a polymer-folding mechanism to develop a new and versatile kind of solid polymer electrolyte (SPE) that currently offers proton conductivity faster than Nafion by a factor of 2, the benchmark for fuel cell membranes. They collaborated with Kenneth B. Wagener, George B.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

Understanding what drives energy demand across the socioeconomic distribution of Singapore households can provide insight on the future energy demand of urban populations in the region’s cities as incomes rise. This is important for policymakers when forecasting and influencing future emissions paths in the context of climate change.
