Size-Effect Of Pd Nanoparticles Supported On Zro2 In The Catalytic Reduction Of No By H2, Young Woo Joh
Size-Effect Of Pd Nanoparticles Supported On Zro2 In The Catalytic Reduction Of No By H2, Young Woo Joh
HIM 1990-2015
Size-selected Pd nanoparticles were synthesized by the reverse-micelle encapsulation method and deposited on a ZrO2 support for the catalytic NO reduction by H2. All of our samples were found to be highly selective, but a significant size effect was not seen for Pd nanoparticles of between 1.2 nm and 5.5 nm. Ultra-small Pd clusters of less than 1 nm were found to be much less active, and are assumed to be affected by an encapsulation effect of the support. Catalyst activity was comparable to that of literature, and is applicable to H2-SCR research.
