Show moreIn this work we made nanoscale uniform deposition of Pd based anode catalyst on the transition metal Au (with atomic ratio Pd:Au=1:10) support of direct liquid ethanol
fuel cells (DLEFCs) and direct liquid formic acid fuel cells (DLFAFCs). Synthesizing
with uniform dispersion and catalyst nanoparticle dimensions understand the role of Pd
reaction on its support in the direct EOR (ethanol oxidation reaction) and FOR (formic
acid reaction) pathways, we performed in situ Pd K-edge X-ray absorption spectroscopy
measurements as a function of potential using a custom-designed flow cell with the
catalyst deposited on the glassy carbon window. We did in-situ EXAFS to better
understand the reaction mechanism of Pd1@Au10 anode catalyst with EOR and AOR in
nanoscale. Compared EOR with FOR electrochemical performance showed Pd@Au&C
played better in ethanol than HCOOH and more stable which the the current density can
reach up to 1216.25 mA·mg-1 Pd of EOR with Pd1@Au10&C in 1M KOH+1M EtOH
(CH3CH2OH) on the ethanol fuel cells (DLEFCs), and 3.56 times higher of the EOR
current compared with commercial Pd@C Show less
