Palladium Paste Nanocomposite Electrode as a New Metallic Electrocatalyst for Ethanol Oxidation and Nonenzymatic Amperometric Sensor in Alkaline Medium

Abstract: Palladium paste nanocomposite electrode was employed as an efficient electrocatalyst for ethanol oxidation and nonenzymatic amperometric ethanol sensor, in alkaline media. The combined application of unique properties of nanomaterials and ionic liquids results in electrodes with interesting advantages compared to the conventional Pd disk electrodes. High tolerance towards accumulation of carbonaceous species (CO‐like intermediates) and poisoning by strongly adsorbed species suggests this electrode suitable for… Show more

“…Catalisadores à base de Pd podem ser uma alternativa viável para a oxidação de álcoois [178,208,[216][217][218], porém, a atividade catalítica e estabilidade do catalisador puro de Pd é crítica e o seu desempenho deve ser melhorado [218]. O tamanho nanométrico é frequentemente um requisito necessário [208], mas apenas esta característica não é suficiente para assegurar uma elevada atividade catalítica, durabilidade e estabilidade de um catalisador.…”

“…Na varredura positiva de potencial os picos XIII a , XV a e XVII a são atribuídos à oxidação direta das espécies do álcool adsorvidas no eletrodo [211]. Na varredura negativa, a corrente observada está associada à oxidação das espécies intermediárias que não foram completamente oxidadas na varredura positiva, ou ainda, à oxidação de espécies recém O comportamento linear entre I p vs ‫ݝ‬ pode indicar que o processo de eletro-oxidação do glicerol obedece à relação de Langmuir (equação 7.9), correspondente a um processo controlado por adsorção [217,[237][238]. …”
