Several factors can influence oxygen mobility in catalytic materials:
Crystal Structure: The arrangement of atoms in the crystal lattice can create pathways or barriers for oxygen movement. Temperature: Higher temperatures generally increase oxygen mobility by providing the necessary energy for atoms to overcome diffusion barriers. Doping: Introducing foreign atoms into the catalyst can create oxygen vacancies or alter the electronic structure, thereby affecting oxygen mobility. Surface Area: Catalysts with higher surface areas provide more active sites for oxygen exchange, enhancing mobility.
