Abstract
Porous Ba-doped Pd/γ-Al2O3 hollow microspheres were successfully synthesized via a simple hydrothermal method with the assistance of lysine, barium and NH4HCO3. The introduction of lysine and NH4HCO3 is beneficial to the formation of porous hollow microspheres and the promotion of specific surface area. The addition of BaO effectively improves the surface basicity of catalysts. The obtained porous Pd/Ba-γ-Al2O3 hollow microspheres are about 5–6 μm in diameter and shell thickness of 1 μm. The porous Pd/Ba-γ-Al2O3 hollow microspheres also exhibit higher catalytic activity for CO and C3H8 oxidation compared with the one without adding lysine and NH4HCO3.
