Abstract: In this study, we synthesized platinum (Pt) nanoparticles (NPs) loaded onto three-dimensional (3D) graphene for hydrogen (H2) sensing using a polymer-assisted hydrothermal (HT) method. The highly porous Pt-3D graphene configuration was sufficiently stable to avoid collapsing during synthesis. It was then deposited onto a microheater to fabricate a H2 sensor. The resulting H2 sensor had high sensitivity, fast response/recovery, less hysteresis, and good linearity.
