New nickel catalyst converts GHG into chemical feedstock more efficiently

New nickel catalyst converts GHG into chemical feedstock more efficiently

September 16, 2017 |

In Washington, scientists at Pacific Northwest National Laboratory are transforming greenhouse gas into chemical feedstock using a new nickel catalyst that operates in water. The new catalyst converts carbon dioxide to formate and has three big advantages compared to traditional carbon dioxide conversion processes. First, it uses water instead of toxic solvents. Second, the catalyst […]

Discovery could lead to new catalyst design to reduce nitrogen oxides in diesel exhaust

Discovery could lead to new catalyst design to reduce nitrogen oxides in diesel exhaust

September 16, 2017 |

In Indiana, researchers discovered a new reaction mechanism that could be used to improve catalyst designs for pollution-control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust. The research focuses on a type of catalyst called zeolites, workhorses in petroleum and chemical refineries and in emission-control systems for diesel engines. New catalyst […]

International consortium uses bio-engineering and mutations for improving biofuel producing bacterial enzymes

International consortium uses bio-engineering and mutations for improving biofuel producing bacterial enzymes

September 16, 2017 |

In Washington, DC, the American Institute of Physics reported that CellulosomePlus, an international research consortium that includes researchers from Spain, Poland and Ireland, developed a way to re-engineer the bacterial enzyme complexes, called cellulosomes, which serve as catalysts in the degradation process. Helping bacteria become more efficient in this process could result in more affordable […]

Catalysts and Enzymes in Biofuel Production

Catalysts and Enzymes in Biofuel Production

June 6, 2016 |

By Elizabeth E. Hood, PhD and Lorenz Bauer, PhD, Lee Enterprises Consulting, Inc. Special to The Digest Introduction An important mitigation strategy for the impact of fossil fuels on the environment is to use biofuels from renewable sources for transportation. The problem is that the cost of biofuel production is high and this nascent industry cannot […]

New ORNL catalyst addresses engine efficiency, emissions quandary

New ORNL catalyst addresses engine efficiency, emissions quandary

September 19, 2015 |

In Tennessee, a catalyst being developed by researchers at the Department of Energy’s Oak Ridge National Laboratory could overcome one of the key obstacles still preventing automobile engines from running more cleanly and efficiently. The mixed oxide catalyst could solve the longstanding problem of inhibition, in which nitrogen oxides, carbon monoxide and hydrocarbons effectively clog […]

Argonne scientists improve catalyst efficiencies

Argonne scientists improve catalyst efficiencies

August 21, 2013 |

In Illinois, for the past four years, Argonne chemist Chris Marshall and his colleagues at the Argonne-led Institute for Atom-Efficient Chemical Transformations (IACT) have been searching for ways to improve the efficiency and selectivity of catalysts – precisely tailored chemicals that help to carry out a vast array of reactions. One of the most notable […]

“Nanobowls” hold key for inorganic catalysts

“Nanobowls” hold key for inorganic catalysts

January 21, 2013 |

In Illinois, “nanobowls” that enable inorganic catalysts to operate selectively may hold the key to improved catalyst performance that can be tailored to accept certain molecules and reject others, demonstrates a joint project by Northwestern University and the DOE’s Argonne National Laboratory. The processing techniques used to develop these flexible nano bowls is scalable and […]

16 yr old develops novel catalyst, converting waste platsic to fuel

16 yr old develops novel catalyst, converting waste platsic to fuel

July 2, 2012 |

In the UK, a 16-year-old Egyptian student has developed a novel catalyst that produces methane, propane and ethane by breaking down waste plastic – products that are then converted into fuel ethanol. “Plastic waste is a real problem in Egypt — and in most developing countries — and this project is simply converting the problem […]

New, edge-only catalysts may open new doors for fuel cells

New, edge-only catalysts may open new doors for fuel cells

February 13, 2012 |

In California, researchers at the University of California-Berkeley have designed a catalyst composed only of edges, that can catalyze the production of hydrogen from water as readily as the edges and defects in regular catalysts. In an article appearing in this week’s edition of Science, the team has created materials with billions of active sites […]
