Redox TGA cycles were performed with 90 mLPM of gas by alternating H2 and air until the weight change achieved equilibrium with a 10 min Ar purge between the air/H2 gases for safety. Oxygen storage capacity was calculated using equation (10) 𝑂𝑥𝑦𝑔𝑒𝑛 𝑠𝑡𝑜𝑟𝑎𝑔𝑒 𝑐𝑎𝑝𝑎𝑐𝑖𝑡𝑦 = 𝑤𝑒𝑖𝑔ℎ𝑡 𝑖𝑛 𝑎𝑖𝑟 -𝑤𝑒𝑖𝑔ℎ𝑡 𝑖𝑛 𝐻 2 𝑤𝑒𝑖𝑔ℎ𝑡 𝑖𝑛 𝑎𝑖𝑟 (10)
