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.

RIKEN researchers develop bio-inspired catalyst that splits water at neutral pH

Green Car Congress

Plants use photosynthesis to convert carbon dioxide and water into sugars and oxygen. The process starts in a cluster of manganese, calcium and oxygen atoms at the heart of a protein complex called photosystem II, which splits water to form oxygen gas, protons and electrons. —Yamaguchi et al.

ASU and Argonne researchers report progress on artificial leaf for solar conversion of water to H2 and O2

Green Car Congress

Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel (Bio-inspired Solar fuel production)—the Energy Frontier Research Center, funded by the Department of Energy, in the Department of Chemistry and Biochemistry at Arizona State University.

Mercedes-Benz 2014 E250 BlueTEC sedan estimated EPA rated at 45 mpg highway, 28 mpg city

Green Car Congress

The Mercedes-Benz 2014 E250 BlueTEC sedan, the first diesel E-Class to be available with 4MATIC, achieves an estimated EPA rating of 45 mpg US (5.2 2014 E250 BlueTEC. When AdBlue is injected into pre-cleaned exhaust gas, ammonia (NH 3) is released, converting nitrogen oxides into nitrogen and water in a downstream catalytic converter.

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. The new catalyst material improves the efficiency of that process, depicted in the schematic below.

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.

Efficient one-pot process to convert bio-oil fractions to gasoline-range hydrocarbons

Green Car Congress

A team at South China University of Technology has developed a one-pot process to convert the diesel distillate and residual oil fractions in bio-oil into high-quality fuels by catalytic hydrocracking with combined CoMoS/Al 2 O 3 and HZSM-5 catalysts. The light fraction is mostly water. of saturated naphthene; 23.4% 2015.05.002.
