SISTEMAS FFCLRP-USP
O LEEA é um dos laboratórios de Pesquisa do Departamento de Química da Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, USP. O seu objetivo principal é a investigação de processos eletroquímicos que ocorrem na interface eletrodo/solução e o papel dos materiais eletródicos nestes processos. As linhas de pesquisa desenvolvidas no LEEA abrangem principalmente a Eletrocatálise e a Eletroquímica Ambiental. Na área de Eletrocatálise são estudadas reações de eletrooxidação de moléculas orgânicas e a reação de redução de oxigênio visando o entendimento dos processos eletródicos e o desenvolvimento de eletrodos eficientes para a aplicação em células a combustível. Também é objetivo do LEEA estudar e desenvolver materiais eletródicos para a aplicação na degradação de compostos tóxicos presentes em diversos tipos de efluentes industriais.
The LEEA is one of the research laboratories of the Department of Chemistry at the Faculty of Philosophy, Sciences and Letters at Ribeirão Preto, USP. Its main objective is the investigation of electrochemical processes that occur at the electrode / solution interface and the role of electrodic materials in these processes. The research lines developed in LEEA mainly cover the Electrocatalysis and Environmental Electrochemistry. In Eletrocatalysis area organic molecules electrooxidation reaction and the oxygen reduction reaction are studied aiming at understanding the electrodic processes and the development of efficient electrodes for their application in fuel cells. It is also aim of LEEA studying and developing electrodic materials for application in the degradation of toxic compounds present in various types of industrial effluents.
