Effects of catalyst surface and hydrogen bond on ethanol dehydrogenation to ethoxy on Cu catalysts

- Reaction barrier for ethanol to ethoxy is the smallest on clean Cu(1 0 0) surface.
- H-bond lowers the reaction barrier for ethanol to ethoxy on Cu(1 1 1) and Cu(1 1 0).
- Ethanol to ethoxy occurs on clean (1 0 0) and ethanol-adsorbed (1 1 0) of Cu catalysts.
