Synthesis of AuPd nanoparticle-decorated graphene-coated ZnO nanorod arrays with enhanced photoelectrochemical performance and stability

Abstract

AuPd nanoparticle-decorated graphene-coated ZnO nanorod (ZNR) array electrodes (ZNR@Gr/AuPd) were synthesized via electrostatic self-assembly followed by solution reduction methods.

One-pot, ligand-free, room-temperature synthesis of Au/Pd/ZnO nanoclusters with ultra-low noble metal loading and synergistically improved photocatalytic performances

“…2e demonstrated that the adjacent lattice fringes of 0.248 nm which were well indexed to the lattice spacing of (101) plane of ZnO, meanwhile the interplanar distances measured from a single AuPd nanoparticle was 0.230 nm, which corresponded to the mean value of (111) planes of face-centred cubic (fcc) Au and Pd. 46 To further investigate the elemental distribution of Au and Pd in the Au/Pd/ZnO nanoclusters, elemental mappings were collected. As shown in Fig.…”
