Researchers demonstrate a way to remove the potent greenhouse gas from the exhaust of engines that burn natural gas. Today’s catalysts for removing unburnt methane from natural-gas engine exhaust are either inefficient at low, start-up temperatures or break down at higher operating temperatures. A new single-atom catalyst solves both these problems and removes 90% of the methane.

Individual palladium atoms attached to the surface of a catalyst can remove 90% of unburned methane from natural-gas engine exhaust at low temperatures, scientists reported today in the journal Nature Catalysis.

While more research needs to be done, they said, the advance in single atom catalysis has the potential to lower exhau...

Research discovery will enable the manufacturing of biorenewable materials from trees and corn. A team led by University of Minnesota Twin Cities researchers has invented a groundbreaking new catalyst technology that converts renewable materials like trees and corn to the key chemicals, acrylic acid, and acrylates used in paints, coatings, and superabsorbent polymers...

Researchers have developed a system that can transform plastic waste and greenhouse gases into sustainable fuels and other valuable products – using just the energy from the Sun.

The researchers, from the University of Cambridge, developed the system, which can convert two waste streams into two chemical products at the same time – the first time this has been achieved in a solar-powered reactor.

The reactor converts the carbon dioxide (CO2) and plastics into different products that are useful in a range of industries...

Ammonia (NH3) has attracted attention in recent years as a carbon-free fuel that does not emit carbon dioxide. For use as a fuel, it should have a lower combustion temperature and produce only nitrogen (N2) and water. Now, researchers have succeeded in developing a new catalyst that burns NH3 at a low temperature and produces N2. The results are expected to contribute to climate change countermeasures and increased renewable energy use.

NH3 is a combustible gas that can be widely used in thermal power generation and industrial furnaces as an alternative to gasoline and light oil...
