Au nanoparticles are efficient catalysts for selective
oxidations.
The interaction between Au nanoparticles and supports is critical
for achieving high catalytic activity. Herein, Au nanoparticles are
supported on a zeolitic octahedral metal oxide based on Mo and V.
The charge of Au is controlled by the surface oxygen vacancies of
the supports, and the redox property of the zeolitic vanadomolybdate
is highly dependent on Au loading. The Au-supported zeolitic vanadomolybdate
is used as a heterogeneous catalyst for alcohol oxidation under mild
conditions with molecular oxygen as an oxidant. The supported Au catalyst
can be recovered and reused without the loss of activity.
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.
