Preparation of porous LaFeO3 microspheres and their gas-sensing property

- Porous LaFeO3 microspheres have been successfully synthesized by a convenient and effective hydrothermal method.
- The synthesis method has the advantages of controllable fabrication, simple equipment and no additional template.
- The mechanism for the formation of porous LaFeO3 microspheres has been explained in accordance with the Ostwald ripening process.
- The as-prepared porous LaFeO3 microspheres exhibited potential applications in monitoring acetone gas.
