SYNTHESIS OF THERMALLY STABLE METAL-OXIDE HYBRID NANOCATALYST WITH ENCAPSULATION OF Pt and Ru NANOPARTICLES

摘要

In this paper, we present the synthesis of ultra-thin titania-coated supported-Pt and Ru hybrid nanocatalysts. It is highly desirable to explore the feasibility of our design to transform various important metal nanoparticles (Pt, Ru, Rh, PtNi etc.) into high-temperature stable catalysts. Herein, we focus on Pt- and Ru Ru-based nanocatalysts, and investigate their relative thermal stability and surface analysis by XPS. This structural investigation could be helpful for the rational design of heterogeneous catalysts that have high thermal and chemical stability.
