Journal ArticleDOI
Electrocatalytic activity of metal phthalocyanines for oxygen reduction
TL;DR: In this paper, a comparative study of the electrocatalytic activity of metallophthalocyanines for O2 reduction in alkaline and acid media was conducted using H2Pc, VOTsPc and CrTsPc.
Journal ArticleDOI
Transition metal macrocycles supported on high area carbon: pyrolysis-mass spectrometry studies
Daniel Alberto Scherson,Auro Atsushi Tanaka,S. Gupta,Donald A. Tryk,C. Fierro,R. Holze,Ernest Yeager,R. Lattimer +7 more
TL;DR: In this paper, the effects of heat treatment on the structure and overall properties of cobalt and iron porphyrins are not well understood, however, the results obtained with several pyrolysis have indicated that the fraction of volatile nitrogen to non-nitrogen containing species generated during the heat treatment is much higher for the metal-free than for the iron-μ-oxo or CoTMPP.
Journal ArticleDOI
Determination of nitrite in food samples by anodic voltammetry using a modified electrode
Wilney de Jesus Rodrigues Santos,Phabyanno Rodrigues Lima,Auro Atsushi Tanaka,Sônia M.C.N. Tanaka,Lauro T. Kubota +4 more
TL;DR: A glassy carbon (GC) electrode modified with alternated layers of iron(III) tetra-(N-methyl-4-pyridyl)-porphyrin (FeT4MPyP) and copper tetrasulfonated phthalocyanine (CuTSPc) was employed for nitrite determination by differential pulse voltammetry (DPV).
Journal ArticleDOI
Amperometric sensor for nitrite using a glassy carbon electrode modified with alternating layers of iron(III) tetra-(N-methyl-4-pyridyl)-porphyrin and cobalt(II) tetrasulfonated phthalocyanine.
Wilney de Jesus Rodrigues Santos,Aline L. Sousa,Rita de Cássia Silva Luz,Flavio Santos Damos,Lauro T. Kubota,Auro Atsushi Tanaka,Sônia M.C.N. Tanaka +6 more
TL;DR: The development of a highly sensitive amperometric sensor for nitrite using a glassy carbon electrode modified with alternated layers of iron(III) tetra-(N-methyl-4-pyridyl)-porphyrin and cobalt(II) tetrasulfonated phthalocyanine and the sensor was found to be tolerant against these ions.
