Hollow semiconducting metal oxide nanoparticles for gas sensing

cecilia-imageThis project is carried out in collaboration with Prof. Dr. Diogo Volanti from São Paulo State University (UNESP), Brazil and it is funded by São Paulo Research Foundation (FAPESP, grant no. 18/08271-7).

Semiconducting metal oxides (SMO) have been extensively applied as gas sensors for the detection of several toxic, pollutant, and flammable gases.  The gas sensing performance of SMO strongly depends on the composition, particle size, surface area and morphology. Therefore, the design of hollow structured nanomaterials can be a promising approach to improve the gas sensing parameters of such materials. In this project, we aim at using hollow structured rare-earth oxides (CeO2 and Pr6O11) as gas sensors and establish a structure function relationship.
