Methane atoms
WebHalomethane. Halomethane compounds are derivatives of methane ( CH4) with one or more of the hydrogen atoms replaced with halogen atoms ( F, Cl, Br, or I ). Halomethanes are both naturally occurring, especially in marine environments, and human-made, most notably as refrigerants, solvents, propellants, and fumigants. Web15 mrt. 2024 · We design and synthesise a series of single-atom catalysts, characterise them and study the impact of exsolution in the dry reforming of methane at 700–900 °C. The catalysts' performance increases with increasing reaction time, as the rhodium atoms migrate from the subsurface to the surface.
