Washington, August 29: In a groundbreaking study, scientists have identified a catalyst that efficiently breaks the C-F bond and converts it to a carbon-hydrogen bond, rendering it harmless to the environment, which might lead to eco-friendly Teflon cookware.
Though the strength of the C-F bond makes it useful in so many applications apart from Teflon cookware, it also gives a formidable greenhouse gas effects that persists in nature.
“The C-F bond is difficult to transform into other bonds under mild conditions because it is inert and unreactive; it’s a challenge to chemists,” said lead author chemist Oleg Ozerov, who conducted the research with postdoc Christos Douvris.
