Methods for tailoring an oxygen defect concentration, such as oxygen vacancies, in a transition metal oxide and the resulting materials are provided. An epitaxial strain, such as in the form of a biaxial tensile strain of up to 5%, is applied to the transition metal oxide to increase the oxygen defect concentration in the transition metal oxide to result in a product comprising the transition metal oxide having an increased oxygen defect concentration.
