Coexistence of Au single atoms and Au nanoparticles on NiAl-LDH for selective electrooxidation of benzyl alcohol to benzaldehyde

We report the coexistence of Au SAs and Au NPs on NiAl-LDH (Au 1+ n -NiAl-LDH) with the Au NPs (∼5 nm) surrounded by abundant Au SAs. For BAOR, the Au NPs can offer adsorption sites for BA and the Au SAs can promote the dehydrogenation process.
