a Quasi in-situ EPR spectra of physical mixtures of AlOOH-900 and different Cu precursors in Ar-H2O atmospheres for 24 h. b EPR spectra of Cu(OH)2-AlOOH-900 before (PM) and after water immersion (IM) for 24 h. EDX mapping images over Cu(OH)2-AlOOH-900 (c) before and (d) after water immersion for 24 h. e, f HADDF-STEM images of Cu(OH)2-AlOOH-900 after water immersion for 24 h. g Scheme of the effect of migration species on the redispersion process.
