a, b Nitrogen physisorption analysis at 77 K for pore occupancy by three ILs: a Sorption isotherm with log-scale relative pressure to highlight the microporous region, b volumetric pore size distribution, c mass evolution of catalyst layers containing various ILs with IL/C ratio of 1.28 measured using capillary penetration method. d Zeta potential measurements for pristine and IL-modified Pt/C with and without Nafion (error bars represent standard deviation of the mean).
