“In the present work, we synthesize uniformly dispersed Pt nanoparticles on inexpensive 3D open-pore carbon foam support using electrodeposition and optimize its catalytic activity for HER reaction. We elucidate the dependence of Pt nanoparticle diameter, density, and mass loading on electrodeposition potential and deposition charge density. The Pt/CF catalyst with loading as low as 0.06 mg/cm2 (~10-fold lower than state-of-the-art commercial electrodes) yield the highest mass and surface area specific activity that is six and 67 times the activity of commercial Pt/C catalyst tested under similar conditions. Moreover, the Pt/CF catalyst also demonstrate highly stable HER activity in acidic conditions after a continuous long-term chronopotentiometry run at high current density ”
