| Abstract: | Vapor deposited (TPP)H 2 film on iron was investigated by means of XPS, SEM, STM and potentiodynamic measurement. It was found that a well distributed deposited film as base layer was formed at initial stage, then growth of the film on the base layer in particle form. The film is composed of a physically adsorbed outer layer and chemically bonded inner layer of (TPP)H 2. The outer layer can be easily removed by DMF solvent. However, Iron porphyrin could not be found on the treated sample surfaces. A model about the structure and composition of the(TPP)H 2 deposited film is put forward. |
