| Abstract | Metal nanoparticlesare currently used in a variety of applications,ranging from life sciences to nanoelectronic devices to gas sensors.In particular, the use of palladium nanoparticles is gaining increasingattention due to their ability to catalyze the rapid dissociationof hydrogen, which leads to an excellent response in hydrogen-sensingapplications. However, current palladium-nanoparticle-based sensorsare hindered by the presence of hysteresis upon hydride formationand decomposition, as this hysteresis limits sensor accuracy. Here,we present a robust colloidal synthesis for palladium–goldalloy nanoparticles and demonstrate their hysteresis-free responsewhen used for hydrogen detection. The obtained colloidal particles,synthesized in an aqueous, room-temperature environment, can be tailoredto a variety of applications through changing the size, ratio of metals,and surface stabilization. In particular, the variation of the viscosityof the mixture during synthesis resulted in a highly tunable sizedistribution and contributed to a significant improvement in sizedispersity compared to the state-of-the-art methods. |
