Bimetallic PtRu alloy nanocrystal-functionalized flower-like WO3 for fast detection of xylene

Bimetallic nanocrystals (NCs) have received a lot of attention due to its excellent catalytic performance. Here, PtRu NCs were successfully synthesized by ethylene glycol and used to modify flower-like WO3 which was prepared via a simple hydrothermal method. The morphology and structure of the as-synthesized materials were characterized, and the performance of the gas sensor based on PtRu NCs decorated WO3 was carefully studied. The gas sensing...
