P. Ferreira Group
The group focuses on the study of the atomic structure, atomic composition and defect behaviour of nanomaterials, through aberration-corrected TEM/STEM and in-situ TEM/STEM, coupled with EELS/EDS and DPC. In particular, the group is interested in understanding the relationships between the atomic structure, composition and the properties of nanomaterials, and the fundamental mechanisms governing the behaviour of materials. The material systems of interest include battery materials, catalyst nanoparticles for proton exchange membrane fuel cells (PEM-FC) and water electrolysis, as well as 2D materials.
Research lines:
- Atomic structure, composition and charge distribution of cathode and anode materials, as well as electrode/electrolyte interfaces, in Li-ion and Na-ion batteries
- Degradation of nanocatalysts and supports for proton exchange membrane fuel cells and water electrolysis
