China team develops efficient multifunctional catalyst for conversion of CO2 to gasoline-range hydrocarbons

Green Car Congress

This catalyst exhibited 78% selectivity to C 5 -C 11 as well as low (4%) CH 4 at a CO 2 conversion of 22% under industrial relevant conditions. Moreover, the multifunctional catalyst exhibited a remarkable stability for 1,000 h on stream, showing potential to be a promising industrial catalyst for CO 2 conversion to liquid fuels.

Sandia-led team demonstrates two efficient hybrid biochemical routes for lignin conversion to value-added chemicals

Green Car Congress

A Sandia National Laboratories-led team has demonstrated two new routes to lignin conversion that combine the advantages of earlier methods while minimizing their drawbacks. Conversely, harsh chemicals can deconstruct lignin in hours or even minutes. Together, Singh reports, these chemicals have a combined market value of $255.7

UCSD, South 8 team report improved liquefied-gas electrolytes for Li-metal batteries

Green Car Congress

Improvements to a class of battery electrolyte first introduced in 2017—liquefied gas electrolytes—could pave the way to replacing the graphite anode with a lithium-metal anode. cycling efficiency reported in the 2017 Science paper, and an 85% cycling efficiency for lithium metal anodes with a conventional (liquid) electrolyte.

Cambridge team demonstrates light-driven photoreforming of unprocessed biomass to H2 at room temperature

Green Car Congress

Biomass conversion is one of the most affordable routes to generate sustainable H 2 , but this process requires the demanding chemical transformation of lignocellulose. In the interest of increasing the selectivity and efficiency of this conversion, it is possible to replace the thermal input with sunlight. Wakerley, Moritz F.

New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

In recent years a team at the University of St Andrews has been exploring metal nanoparticles prepared by redox exsolution at the surface of perovskite oxides and have shown these structures to enable new dimensions in catalysis and energy conversion and storage technologies owing to their socketed, well-anchored structure. (In

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

Solar-to-chemical energy conversion for energy storage, fuels and feedstocks, particularly to address greenhouse gas emissions, is one of the primary goals for scientists in the field of solar energy generation. QDs, which are spherical semiconductor nanocrystals (2-10 nm in diameter), enhance the MEG process. Crisp, Jing Gu, Boris D.

Researchers in Japan propose a more efficient method to reduce radioactive waste; fast reactor system shortens the lifetime of LLFPs

Green Car Congress

Transmutation is a change induced by neutron capture that results in the conversion of LLFPs to short-lived or non-radioactive nuclides. Minor actinides are elements synthesized in nuclear fuel other than uranium and plutonium, such as neptunium, americium and curium.
