Sónia Gonçalves Patrício

Assistant Researcher


Sónia graduated in Chemistry in 2005 by Faculty of Science from University of Oporto (FCUP) and received the "best chemistry student award" from "Engenheiro António de Almeida" Foundation. By the end of 2011, she completed her PhD in Chemistry at FCUP, in the field of Materials Science. During her doctoral, she developed expertise in material synthesis and surface modification by bottom-up approach (layer-by-layer technique) for chemosensing applications. She also specialized in several characterization techniques, with emphasis in electrochemistry.

Currently, she is post-doctoral researcher at CICECO from University of Aveiro. Her current research interest focuses on the development of advanced ceria-based composite microstructures for CO2 separation membranes, especially aimed at being used in fossil-fueled power plants. She is also exploiting a comprehensive understanding of the multi-ionic transport mechanism of these composites towards novel electrochemical advanced applications.

In 2012, Sónia received the best poster award in the International Conference Electroceramics XIII (Enschede, Netherlands).

Domain of specialization

  • Material synthesis and surface modification: transition metal complexes, electroactive polymers, hybrid thin films, ceramic-based composites;
  • Spectroscopic methods for elemental charaterization: (UV-Vis, ATR-FTIR, NMR); piezoelectrical techniques: quartz crystal microbalance and crystal impedance; surface chemistry: X-ray diffraction (XRD), dynamic light scattering (DLS), X-ray photoelectron spectroscopy (XPS); microscopy: scanning electron microscopy (SEM) and atomic force microscopy (AFM).
  • Electrochemistry: cyclic voltammetry, impedance spectroscopy and faradaic efficiency;
  • Gas chromatography.

Current research interests

  • Modeling multi-ionic transport properties of ceria-based composite electrolytes : from fuel cell to advanced electrochemical applications;
  • Design of dual-ionic composite membranes with fine-tuned microstructures for carbon capture;
  • Understanding the influence of the microstructural design on the dual-ionic transport, aiming at achieving new guidelines for improving permeation membrane performance;
  • Improvement of the state-of-the-art dual-ionic composite membranes: exploiting novel type of membranes based on similar ionic transport mechanism for other greenhouse gas capture (NOx).
