Composition and Microstructure of Ag 70 Pd 20 Au 10 Alloy Specimens with Etching and Their Catalytic Activity to Decomposition of Hydrogen Peroxide
CATALYSIS LETTERS(2022)
摘要
Arc melted Ag 70 Pd 20 Au 10 alloy specimens etched in concentrated nitric acid were studied using X-ray fluorescence spectroscopy, X-ray diffractometry, scanning electron microscopy and transmission electron microscopy. The response of nanoporous ternary alloy phase obtained from the etching to the catalytic H 2 O 2 decomposition reaction process has been studied at 298 K in aqueous acid and base mediums. The catalysis results obtained from the data analysis were compared with literature reports. Graphical Abstract
