The effect of particle characteristics on catalytic activity. a Initial particle characteristics for the model pellet catalysts with 10 and 30 nm particles presented as a parallel coordinate plot and including: particle diameter d, particle population p, length of the particle–perovskite interface Li and exposed particle area, Ae. b, c Corresponding catalytic activity after activation, for b CO oxidation and c NO oxidation. The catalytic rates are normalised with respect to the area of the pellet decorated with particles (Supplementary Note 3). The values of p, Li and Ae are normalised with respect to the area decorated with particles (given per μm²). The errors are smaller than the points
