Study of the deposition and characterisation of a 5,10,15,20-tetrakis-(4-sulphonatophenyl)porphyrin Co(II) layer at gold surfaces in alkaline solution

In this paper, the electrodeposition of Co(II)TSPor at gold electrodes is described. It was found that this deposition is initially controlled by kinetic parameters leading to a nearly 100% coverage of the electrode surface. However, once formed a reorganisation of the layer occurs.

Zusammenfassung:In this paper, the electrodeposition of Co(II)TSPor at gold electrodes is described. It was found that this deposition is initially controlled by kinetic parameters leading to a nearly 100% coverage of the electrode surface. However, once formed a reorganisation of the layer occurs. Experimental evidence that Co(II)TSPor is deposited was provided by using Raman spectroscopy.
