Visualization of Ethylene Dehydrogenation
These images show a theoretical chemical reaction: the dehydrogenation of ethylene. Two H atoms are removed from the ethylene C2H4 molecule upon interaction with a substrate of Nickel.
- During an ethylene adsorbing phase, the C2H2 moves towards the nickel surface.
- The 2H's start to move away during the surface reaction.
- Hydrogen diffusion then occurs as the hydrogens move further away from the C2H2 which sticks to the surface of nickel.
- Acetylene desorbing occurs when the C2H2 leaves the nickel.
