Tóm tắt The materials currently used in proton-exchange membrane fuel cells (PEMFCs) require complex control of operating conditions to make them sufficiently durable to permit commercial deployment. One of the major materials challenges to allow simplification of fuel cell operating strategies is the discovery of catalyst supports that are much more stable to oxidative decomposition than currently used carbon blacks. Here, we report the synthesis and characterization of advanced nanostructure Ti0.7W0.3O2 prepared via a low-temperature solvothermal process without using any surfactants or stabilizers. A promising doped metal oxide is a candidate for such a durable catalyst support. The synthesized nanoparticles were characterized by XRD, TEM measurements. Results show that Ti0.7W0.3O2 exists in a single-phase solid solution with anatase phase of TiO2. Interestingly, the average particles size approximately 5 nm that could be promised to have a large specific surface area, which is an extremely important factor for promising catalyst support. Moreover, Ti0.7W0.3O2 synthesized at 200 oC for 6 hours obtains the smaller particles size without particles agglomeration compared to previous researches. These results open a new approach for synthesis nanostructure Ti0.7W0.3O2 by a solvothermal process for further application as catalyst support in PEMFCs.
