  1. aCobalt particle size is obtained from TEM analysis using at least 200 Co3O4 nanoparticles and calculated from Co3O4 particle size using Co and Co3O4 densities b Cobalt particle size is calculated from H2-chemisorption assuming the surface stoichiometry H/Co = 1 and an atomic cross-sectional area of 0.0662 nm2.
