Preparation of CuO_x-TiO_2 nano-composite photocatalysts from intercalated layered structure

摘要

Nano-composite photocatalysts, CuO_x-TiO_2, were synthesized from Cu(OAc)_2-intercalated fibrous layered titanates by thermal decomposition in different atmospheres (N_2, air, and H_2). The structural characterization using XRD, UV-vis, XPS, and SEM implied that the composite of partially reduced CuO_x and anatase-type TiO_2 in a waffle-like texture would be a reason for the excellent photocatalytic activity for H_2 production from CH_3OH/H_2O mixtures.
