A novel multifunctional catalyst Cs x H 3−x PW 12 O 40 /CeO 2 was prepared to mitigate the free radical attack to membranes in fuel cell environment. Cs x H 3−x PW 12 O 40 /CeO 2 nanoparticles synthesized by solution-based hydrothermal method and two-step impregnation method were dispersed uniformly into the Nafion ...
By single-step supercritical hydrothermal synthesis method, ceria nanoparticles with diameters of 3–8 nm were successfully supported on multi-wall carbon nanotubes (MWNTs) homogeneously without additional treatment. It was found that the amount and distribution of ceria nanoparticles supported on the MWNTs depended on the pH of reaction mixture. At pH=7, the largest amount of particles was observed...
