Our correlative multimodal approach can link local activity with atomic-scale details of structure, morphology and composition of surface species formed during the oxygen evolution reaction (OER). We found that 6 nm β-CoOOH(01-10) layer, grown on [-12-10]-oriented Co, contains more hydroxyl ions and easily reducible CoIII-O sites, exhibiting a higher OER activity than 3 nm thick β-CoOOH(10-13) formed on [02-21]-oriented Co.
