Abstract:We use field emission scanning electron microscope (FE-SEM) to investigate
the growth of palladium colloids over the surface of thin films of WO3/glass.
The film is prepared by Pulsed Laser Deposition (PLD) at different
temperatures. A PdCl2 (aq) droplet is injected on the surface and in the
presence of steam hydrogen the droplet is dried through a reduction reaction
process. Two distinct aggregation regimes of palladium colloids are observed
over the substrates. We argue that the change in aggregation dynamic… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
