Fig. 3: Physical characteristics of the Pt/cPDA catalyst.

From: Designing fuel cell catalyst support for superior catalytic activity and low mass-transport resistance

Fig. 3

a TEM micrograph of Pt deposited cPDA nanospheres (Pt/cPDA), b PSD histogram of deposited Pt nanoparticles and computationally estimated mass activity of Pt at 0.9 V (im,0.9V vs RHE) digitized from refs. 15, 33. c TGA thermogram of Pt/cPDA and TKK Pt/C (10.2% and 19.8%) catalysts for the determination of Pt content (details in supplementary information), and d STEM images of microtomed Pt/cPDA CL in—(i) and (ii) dark field and (iii) bright field mode. The marked regions are the cross-section of Pt/cPDA catalysts highlighting that the Pt particles are located at the exterior of the cPDA support.
