Platinum‐Decorated Laser‐Induced Graphene Electrodes: Optimizing Hydrogen Evolution Reaction Catalysis through Minimal Platinum Loading

open access: yesChemNanoMat, Volume 12, Issue 1, January 2026.
Laser‐induced graphene electrodes decorated with platinum (Pt) nanoclusters are engineered via magnetron sputtering to optimize hydrogen evolution reaction (HER) catalysis. By tuning Pt deposition time, a minimal Pt loading (60 s) delivers outstanding HER performance, balancing defect density and Pt2+ anchoring for superior mass activity.
