New efficient, low-temperature catalyst for converting water and CO to hydrogen and CO2

Green Car Congress

Scientists in the US and China have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO) via the water-gas shift (WGS) reaction. Its synergy with adjacent Mo sites in α-MoC can effectively activate water at low temperature. —Yao et al.

NCSU team develops catalyst for thermal hybrid water-splitting and syngas generation with exceptional conversion; H2 gas and liquid fuels

Green Car Congress

Researchers at North Carolina State University have developed a highly effective new perovskite-promoted iron oxide redox catalyst for a hybrid solar-redox scheme they had proposed earlier for partial oxidation and water-splitting of methane. doi: 10.1039/C4EE03431G.

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. When immersed in water with visible light irradiation (? ? 400 nm), the mesh produces hydrogen gas. Credit: ACS, Liu et al. Click to enlarge.

Rice University lab study suggests foam may maximize enhanced oil recovery efforts

Green Car Congress

Results of a Rice University laboratory study suggests that using foam may maximize enhanced oil recovery (EOR). of oil from low-permeability regions after four minutes of pushing it through a test rig, versus 53% for water and gas and 98.3% If you lose the foam, it collapses into slugs of gas and liquid.

Molecular shuttle speeds up hydrogen production by the photocatalytic splitting of water

Green Car Congress

water splitting. One approach is to utilize incoming solar radiation for the photocatalytic generation of molecular hydrogen (H 2 ) from water. Photocatalytic synthesis of hydrogen gas from water requires the transfer of electrons to the hydrogen, while the holes interact with the oxygen or are scavenged by other molecules.
