Dr. Keyla Teixeira Santos
Committee Member
Centro Nacional de Pesquisa em Energia e Materiais (CNPEM) – keylats@unicamp.br
Dr. Keyla Teixeira Santos: Her scientific trajectory is centered on electrocatalysis, with an emphasis on understanding reaction mechanisms, as well as the activity and stability of catalysts for energy conversion. During her Ph.D., she conducted a research internship at the University of Oldenburg (Germany), where she applied scanning electrochemical microscopy (SECM) to investigate ionic transfer at immiscible liquid interfaces, focusing on electrocatalytic systems. She carried out postdoctoral research at the Université Grenoble Alpes (France) and at the Universidade Estadual de Campinas (Brazil), working on the development and characterization of electrocatalysts for oxygen and hydrogen reduction and evolution reactions (ORR, HOR, HER, OER), as well as alcohol oxidation, with applications in fuel cells and electrolyzers. Currently, she is a researcher at the Quati beamline at the LNLS-CNPEM, where she studies multimetallic materials and the application of X-ray absorption spectroscopy (XANES/EXAFS) under in situ and operando conditions. Her research combines electrochemical techniques with advanced physicochemical characterization to elucidate relationships between structure, composition, and catalytic performance, including degradation studies under conditions close to real operation.
