Atmospheric scientists show proposed 'geoengineering' effort to remove methane, a potent greenhouse gas, from the atmosphere could worse air quality while providing minimal climate benefits.

Photocatalytic methane conversion and oxidation is an emerging field that ... Moreover, controlling the type of free radicals generated during the photocatalytic reaction has emerged as a ...

The Earth's atmosphere has strengthened its ability to remove air pollutants, including the potent climate-warming gas ...

"It was a major discovery in the 1970s that OH is produced in the troposphere by reactions to allow the oxidation ... particularly methane, says Nichol. "Even though the hydroxyl radicals appear ...

"When that hydrogen peroxide is in the presence of sunlight, it's going to make a really powerful oxidant, the hydroxyl radical ... methane emissions. Artificially speeding up methane oxidation ...
