摘要

Abstract

Microorganism-mediated

hexadecyltrimethylammonium chloride (CTAC)-directed (MCD) method was employed in this work to synthesize Pd nanoflowers (PdNFs). Proper Pichia pastoris cells (PPCs) dosage

ascorbic acid (AA)

Pd(NO

)

and CTAC concentrations were essential for the growth of the PdNFs. The size of the assynthesized PdNFs could be tuned by adjusting the amount of Pd(NO

)

solution and dosage of PPCs used. Characterization techniques such as X-ray diffraction

transmission electron microscopy

and X-ray photoelectron spectroscopy were used to verify the nature of the PdNFs. Finally the PdNF/PPC nanocomposites were immobilized onto TiO

supports to obtain bio-PdNF/TiO

catalysts which showed excellent catalytic activity for CO oxidation

obtaining 100% conversion at 100 ℃ and remaining stable over a period of 52 h of reaction time.
