Contrastive study of structure and photocatalytic performance with three-dimensionally ordered macroporous CuO–TiO2 and CuO/TiO2

A new bimetallic plasmonic photocatalyst consisting of gold(core)-copper(shell) nanoparticle and titanium(IV) oxide support

“…CuO/TiO 2 shows a comparable activity with that of Au/TiO 2 . Visible-light photocatalysis of CuO/TiO 2 has been reported for the degradation of model organic pollutants, 33,34 which can stem from the photo-induced interfacial electron transfer between the surface CuO levels and TiO 2 . 33 Surprisingly, Au@Cu/TiO 2 exhibits a much higher photocatalytic activity than Au/TiO 2 and CuO/TiO 2 .…”

Enhanced visible-light activities for PEC water reduction of CuO nanoplates by coupling with anatase TiO2 and mechanism

“…Moreover, compared with the CuO NPs sample, the 15T/C NPC sample shows a slightly low binding energy value for Cu 2p XPS spectra. These results suggest that a more intense interaction exist between CuO and TiO 2 species in the resultant 15T/C NPC, and the electrons of TiO 2 transfer to CuO since the Fermi level of CuO is lower than that of TiO 2 [23]. In general, the intimate connections and homogeneous dispersion are helpful for effective charge transfers among different constituents in the fabricated nanocomposites.…”

Photocatalytic degradation of trichloroethylene in a continuous annular reactor using Cu-doped TiO2 catalysts by sol–gel synthesis

“…The double peaks at 932.7 and 952.7 eV are attributed to Cu2p3/2 and Cu2p1/2 in CuTiO 3 (CuO·TiO 2 ) [56]. Relative low binding energy value for Cu2p XPS spectra and relative high binding energy value occur due to interactions between CuO and TiO 2 [57], for Ti2p should be ascribed to that the electrons of TiO 2 transfer to CuO since the Fermi level of CuO is lower than that of TiO 2 [56].
