Structural and Optical Interplay of Palladium-Modified TiO 2 Nanoheterostructure
Abstract
The electronic structure and optical properties of Pd-modified TiO2 nanotubes (NTs) with a vertically aligned nanotubular structure grown by a two-step electrochemical anodization method have been studied using X-ray spectroscopy. X-ray absorption near-edge structure (XANES) at the Ti L3,2- and O K-edges was used to investigate the TiO2 NTs before and after Pd modification. It was found that Pd nanoparticles (NPs) are uniformly coated on the NT surface. The Pd L3-edge of the deposited Pd NPs shows a more intense whiteline and a blue shift for the Pd L3-edge absorption threshold relative to Pd metal, indicating charge depletion from the Pd 4d orbital as a result NP formation. The lattice of Pd is slightly contracted upon NP formation, although it remains fcc as revealed by extended X-ray absorption fine structure (EXAFS) analysis at the Pd K-edge. X-ray-excited optical luminescence (XEOL) together with XANES with element and site specificity was used to study the optical luminescence from TiO2 NTs. It was found that the defect-originated XEOL intensity dropped noticeably in the Pd NP-coated NTs, suggesting a Pd NP–TiO2-interaction-mediated reduction in the radiative recombination of electrons and holes. Finally, further evidence is provided by Ti 2p resonant inelastic X-ray scattering (RIXS), inmore »
