What did we learn from the TPD studies?

What do we want to know about these reactions?

• What type of surface site reacts with CCl4?

• How do Cl biproducts inhibit the reaction?

• Sorbed Cl biproducts of the reaction inhibit further reaction.

• This reaction likely occurs at regular lattice sites

• CCl4 readily reacts with the Fe3O4(111) surface to

predominantly form OCCl2
