New single-atom catalyst removes methane from engine exhaust at lower temperatures, while remaining stable at high temperatures

Green Car Congress

A new study by researchers from Washington State University and SLAC National Accelerator Laboratory has found that a catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures. The work is published in the journal Nature Catalysis.

New exhaust catalyst features thermal durability and high reactivity at low operating temperatures

Green Car Congress

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water.

Researchers develop effective exhaust catalyst for lower temperature exhaust

Green Car Congress

To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of waste heat in the exhaust. As a result, future generations of exhaust after-treatment catalysts must perform at temperatures that are 100 °C lower than current catalysts. —Nie et al. —Yong Wang.

Polish study links pollution and winter with rise in heart attack treatment

Green Car Congress

Heavily polluted areas have a higher rate of angioplasty procedures to treat blocked arteries than areas with clean air, according to research to be presented at ESC Congress 2019 together with the World Congress of Cardiology. Procedures are even more common in winter, the most polluted time of year. additional PCIs per week.

Study provides more insight into air pollution mechanisms that cause cardiovascular diseases

Green Car Congress

Air pollution, and fine dust in particular, is calculated to contribute to more than four million deaths each year. While the mechanisms by which air pollutants cause cardiovascular events is undergoing continual refinement, the preponderant evidence support rapid effects of a diversity of pollutants including all particulate pollutants (e.g.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

In a recent open-access paper published in ACS’ Environmental Science & Technology , researchers from the University of York report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. the products used for “car care,” such as windshield washer fluid.
