Characterization of a highly sensitive and selective hydrogen gas sensor employing Pt nanoparticle network catalysts based on different bifunctional ligands

•Bifunctional ligand-linked Pt-nanoparticles as the catalyst for thermoelectric combustible hydrogen gas sensor.•Comparative characterization of catalysts with five different bifunctional ligands.•Extremely high sensitivity, 400 mV/1% vol., around double than the similar previous work.•650 ms respon...
