Incorporation of Gold into Porous Anodic Alumina Formed on an Al–Au Alloy

Abstract: An Al−1 atom % Au gold alloy is employed to investigate the incorporation of a nonoxidized alloying element into porous anodic alumina films formed in phosphoric acid and sulfuric acid electrolytes. Gold is shown to enrich in the alloy in the initial stages of film growth, when a gold-free film is formed. On sufficient enrichment of the alloy, gold nanoparticles are incorporated into the film above an enriched alloy layer containing nanocrystals of Al 2 Au. The formation of the nanoparticles is accompanied by … Show more

“…The chemical dissolution near the top surface layer is faster and thus contributes more to the fact that the walls become thinner towards the top of nanotubes [8]. In order to avoid the influence of chemical dissolution on the top surface and keep the patterned stripes around the concaves unchanged, the duration of two-step anodization was controlled for only 900s on purpose, because chemical dissolution can be negligible for the present anodizing conditions involving short anodizing periods [25]. if the field-assisted dissolution or preferential oxide dissolution existed at the pore bottom, the field-assisted dissolution rate should be very high (3500/15=233 nm/min), based on the field-assisted dissolution [5,8,18].…”

“…If there were no other types of currents (such as, electronic current), the nanotube length should be directly proportional to the total anodizing current (J total ) or the total electric charge (Q) [25]. If this were true, based on the nanotube length of 1.…”
