Carbon Material and Cobalt-Substitution Effects in the Electrochemical Behavior of LaMnO3 for ORR and OER

Flores-Lasluisa, Jhony X.; Huerta, Francisco; Cazorla-Amorós, Diego; Morallon, Emilia (MDPI AG, 2020-12)

[EN] LaMn1-xCoxO3 perovskites were synthesized by a modified sol-gel method which incorporates EDTA. These materials' electrochemical activity towards both oxygen reduction (ORR) and oxygen evolution reactions (OER) was ...
Hematite as an Electrocatalytic Marker for the Study of Archaeological Ceramic Clay bodies: A VIMP and SECM Study**

Doménech-Carbó, Antonio; Giannuzzi, Michele; Mangone, Annarosa; Giannossa, Lorena Carla; Di Turo, Francesca; Cofini, Elena; Domenech Carbo, Mª Teresa (John Wiley & Sons, 2022-01-27)

[EN] The electrocatalytic effect exerted by hematite, a ubiquitous component of clay bodies, on the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) can be used to acquire information on archaeological ...
Manganese oxides/LaMnO3 perovskite materials and their application in the oxygen reduction reaction

Flores-Lasluisa, Jhony X.; Huerta, Francisco; Cazorla-Amorós, D.; Morallón, E. (Elsevier, 2022-05-15)

[EN] Manganese-based materials can catalyze the oxygen reduction reaction (ORR), although their activity is known to depend on the crystalline phases and on the concentration of surface-active species. In the present study, ...
Study of the sensitisation of a highly alloyed austenitic stainless steel, Alloy 926 (UNS N08926), by means of scanning electrochemical microscopy

Leiva García, Rafael; Akid, R.; Greenfield, D.; Gittens, J.; Muñoz Portero, María José; García Antón, José (Elsevier, 2012-05-30)

The feedback mode of a scanning electrochemical microscope (SECM) was applied to study differences in the reactivity of a highly alloyed austenitic stainless steel, Alloy 926 (UNS N08926), in its unsensitised and sensitised ...
Transition metal oxides with perovskite and spinel structures for electrochemical energy production applications

Flores-Lasluisa, J. X.; Huerta, Francisco; Cazorla-Amoros, D.; Morallón, E. (Elsevier, 2022-11)

[EN] Transition metal oxide-based materials are an interesting alternative to substitute noble-metal based catalyst in energy conversion devices designed for oxygen reduction (ORR), oxygen evolution (OER) and hydrogen ...
Understanding the chemisorption-based activation mechanism of the oxygen reduction reaction on nitrogen-doped graphitic materials

Ferre Vilaplana, Adolfo; Herrero, Enrique (Elsevier, 2016-06-20)

[EN] To optimize nitrogen-doped graphitic materials as metal-free catalysts for the oxygen reduction reaction mechanisms have to be better understood. Here, the role played by pyridinic nitrogen-dopants in the chemisorption-based ...
