“In conclusion, we demonstrated a simple solution-processed electrodeposition technique to load low amounts of Pt nanoparticles on low-cost, high surface area 3D carbon foam support for HER reaction. We established the dependence of particle diameter and density as a function of deposition potential and charge density and investigated the HER activity of the Pt-loaded carbon foams. All synthesized Pt/CF catalysts exhibited excellent mass activities that are superior to the state-of-the-art commercial Pt/C catalyst. For the best performing Pt/CF catalyst, the mass and specific activity were 6.3 and 67 times higher than commercial Pt/C catalysts. “
