a O 1s XPS spectra of various InZrOx oxides, in which the abundance of surface oxygen vacancies (Odefect, calculated as Idefect/(Ilattice + Idefect) are labeled (Idefect and Ilattice represent peak area of defect and lattice oxygen, respectively)42. b H2-TPR profiles of various InZrOx oxides (The shadow insert is the enlargement of H2-TPR profiles in the temperature range of 100–250 °C). c Cell volumes of various fresh InZrOx oxides compared to that of H2-reduced ones. d CO2-TPD profiles of various InZrOx oxides.
