INL researchers develop high-performance oxygen electrode for PCEC cell; high-temperature electrolysis

Green Car Congress

Researchers at Idaho National Laboratory have developed a new electrode material for a protonic ceramic electrochemical cell (PCEC) that can efficiently convert excess electricity and water into hydrogen. Water splitting reaction on oxygen electrode and PNC’s hydration. The triple conducting oxide of PrNi 0.5

Virginia Tech team develops process for high-yield production of hydrogen from xylose under mild conditions

Green Car Congress

Percival Zhang, has developed a process to convert xylose—the second-most abundant sugar in plants—into hydrogen with approaching 100% of the theoretical yield. In the process, hydrogen is produced from xylose and water in one reactor containing 13 enzymes, including a novel polyphosphate xylulokinase (XK). earlier post ).

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. The greatest challenge is to develop a suitable technology for large scale and cost effective solar fuel production to compete with fossil fuel.

This is a sponsored article brought to you by NYU Tandon School of Engineering. However, the research team quickly learned that it was difficult to determine when to travel to field sites to collect flood water samples. A common adage is that if you can measure a thing, you can control a thing, or at least manage it. cm) in depth.

New bimetallic copper-titanium hydrogen evolution catalyst outperforms platinum by more than 2x

Green Car Congress

It is widely believed that room temperature electrochemical reduction of water to molecular hydrogen offers a significant promise for supplying CO 2 -free hydrogen, which can be used directly as a fuel or as reactant to convert CO 2 and to upgrade petroleum and biomass feedstocks to value-added chemicals and fuels through hydrotreating processes.

MIT/Tsinghua high-rate aluminum yolk-shell nanoparticle anode for Li-ion battery with long cycle life and high capacity

Green Car Congress

Aluminium should be an attractive anode material for rechargeable Li-ion batteries for many reasons, such as low cost (~$2,000 ton −1 ), high theoretical capacity (2,235 mAh g −1 if Li 9 Al 4 , low potential plateau (~0.19–0.45 V V against Li + /Li 3 ), high electrical conductivity and so on.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

This research article focuses on a highly favored route to the synthesis of controlled nanostructures at high rate, high yield, and low cost by molten carbonate electrolysis. A solution to this challenge is accomplished by the co-generation of a valuable product from the captured carbon, which can offset the carbon capture cost.
