“…Electrolysis of the solution containing [Co II tmtppa] 4 in pH 7 buffer at potentials of the first [14]) and are also typical of ring-based reductions in phthalocyanines [22]. However, the [Co I tmtppa] 3 species shows an absorption in the 500 nm region and the Co(I) oxidation state in the [Co I tmtppa] 3 species has been confirmed before by an electron spin resonance (ESR) spectroscopy signal [14,18].…”

“…Free base meso-tetraphenylsulfonated porphyrin (H 2 TPPS 4 4À ) and metallated meso-tetra(N-methyl-4-pyridyl) porphyrin (MTMePyP 4 + , M=Sn, Mn, Co, In) were synthesized as reported before [35][36][37][38]. Porphyrin nanorods were fabricated by ionic self-assembly of two oppositely charged porphyrins and were prepared and characterized as reported in literature [39,40] …”

Porphyrin nanorods (PNR) were prepared by ionic self-assembly of two oppositely charged porphyrin molecules consisting of free base meso-tetraphenylsulfonate porphyrin (H 4 TPPS 4 2À ) and meso-tetra(N-methyl-4-pyridyl) porphyrin (MTMePyP 4 + M = Sn, Mn, In, Co). ÀMnTMePyP 4 + porphyrin nanorods. The absorption spectra and transmission electron microscopic (TEM) images of these structures were obtained. These porphyrin nanostructures were used to modify a glassy carbon electrode for the electrocatalytic reduction of oxygen, and the oxidation of hydrazine and methanol at low pH. The cyclic voltammogram of PNR-modified GCE in pH 2 buffer solution has five irreversible processes, two distinct reduction processes and three oxidation processes. The porphyrin nanorods modified GCE produce good responses especially towards oxygen reduction at À0.50 V vs. Ag j AgCl (3 M KCl). The process of electrocatalytic oxidation of methanol using PNR-modified GCE begins at 0.71 V vs. Ag j AgCl (
