Trimetallic hybrid nanoparticles with versatile approach to fabricate the ideal nanocatalysts that have industrial applications have recently triggered much research interest. However, the rational fabrication of trimetallic nanocrystals with both fascinating morphology and tunable compositions remain a challenge. In this work, we prepared an aqueous-phase synthesis of hybrid trimetallic–semiconductor by using seed-mediated growth method with metal nanoplates as seeds and by conducting a rapid surface sulfidation process using a sulfur precursor. Their optical properties, morphologies, structures, and chemical compositions were characterized by UV-vis, TEM, XRD and XPS techniques. The results show that the trimetallic hybrid nanoparticles provided better catalytic activity towards the degradation of methylene blue than those obtained from bimetallic nanoparticles and monometallic counterparts due to their abundant surface-active areas as well as the synergistic effects.
