 The use of ruthenium RU as a single atom catalyst has been shown to be effective in reducing the amount of methane produced during the hydrogenolysis of polyolefins. This catalyst is able to reduce the methane yield from 20% to just 2.2% while still producing high yields of liquid fuels. This catalyst also has a high production rate of 314.93 grams per hour per 1 gram of RU. These results suggest that RU single atom catalysts have potential applications in the recycling of plastics into valuable liquid fuels.
