“…11 The development of semiconductor/TiO 2 hetero-structures nanocomposites with {101} and {001} exposed facets can be a key to construct new catalysts. Research on indium oxide (In 2 O 3 ) nanoparticles has attracted much attention in the recent years 12,13 because of its applications in solar cell, field emission display, lithium ion battery, nanoscale bio-sensor, gas sensor, optoelectronics and photocatalysis. [14][15][16][17] In this paper, for the first time, we report that indium oxide nanoclusters supported on nanosized anatase titania can activate molecular oxygen, demonstrating epoxidation of styrene at mild condition.…”

“…According to the previous results reported in the literature, the observed bands at 413 and 557 cm -1 are attributed to In-O stretching in cubic In 2 O 3 whereas the band at 602 cm -1 is the characteristic of In-O bending vibrations in In 2 O 3 [12-14]. Also, the appearance of three bands peaking at 540, 565, and 600 cm -1 can be assigned to the phonon vibration of In-O bonds [15], which indicates the formation of cubic In 2 O 3 . These FT-IR results have good agreement with the XRD analysis experiment results shown in Figure 4.…”

“…The IR bands at 1124 cm À1 and 1051 cm À1 only present in the core-shell ZnO/In x S y NR (0.03 M of Na 2 S) are assigned to the In-OH deformation modes as was reported before when In (OH) 3 was prepared. 33,34 The IR region from $ 900 cm À1 to $ 660 cm À1 is assigned to the Zn-O bond, 35 whose peaks were the same for the 3 samples. XPS/UPS measurements were performed to investigate the surface chemistry and optical properties of the core-shell electrodes.…”

“…Thus, the higher PCE could probably be ascribed to the inhibition of the electron back transfer from the oxide to the redox electrolyte by the insulating oxide. 46,47 Finally, the presence of higher amount of hydroxide groups, which facilitates dye attachment through its carboxylic acid group, could also enhance PCE by increasing the linking sites available for the attachment of the dye. The latter was also observed in other core-shells of TiO 2 with metal hydroxides, where they observed higher dye-adsorption when a shell layer of NaOH was deposited on the TiO 2 48 and a decrease of the back electron recombination when a shell layer of Mg(OH) 2 was used.…”
