Improved Charge Separation and CO2 Affinity of In2O3 by K Doping with Accompanying Oxygen Vacancies for Boosted CO2 Photoreduction

“…The peaks at 469 and 511 nm are ascribed to the radiative recombination of photogenerated holes with electrons that occupied O V . − The lower PL intensity always reflects the lower charge recombination rate . In addition, after K doping into In 2 O 3 , an apparent and broad band centered at 650–700 nm emerges, which is assigned to the increased surface O V on K-doped In 2 O 3 . Therefore, it can be deduced that K doping can effectively accelerate charge separation and transfer of In 2 O 3 , as well as inducing O V .…”

“…The peak band in 500−650 cm −1 is correlated with the phonon or lattice vibrations of cubic phase In 2 O 3 . 20,21 In detail, the peaks at 602.3 and 556.5 cm −1 can be assigned to the In−O asymmetric stretching, 22 and the bands at ∼1635 and 1385 cm −1 are the result of the H−O−H bending vibration. 22,23 The maintained FTIR spectra also corroborate that the K doping has not changed the structure of In 2 O 3 .…”

“…38 In addition, after K doping into In 2 O 3 , an apparent and broad band centered at 650−700 nm emerges, which is assigned to the increased surface O V on K-doped In 2 O 3 . 21 Therefore, it can be deduced that K doping To investigate the catalytic transformation over KIO-3, the in situ FTIR spectra of In 2 O 3 and KIO-3 are recorded in Figures S11 and S12, respectively. In Figure S13, the peaks at the range of 2390−2300 cm −1 are attributed to the vibration of C=O bonds.…”

Aggregate assembly of ferrocene functionalized indium-oxo clusters

“…Indium oxide (In 2 O 3 ) as an n-type semiconductor possesses excellent electronic and catalytic properties, making it highly promising in various fields. 1–3 Many methods have been developed to prepare nano-In 2 O 3 , 4 high-pressure modified In 2 O 3 , 5,6 and indium-containing mixed oxides and zeolites, 7–9 due to their application in sensors, 10 electronics, 11 and catalysis. 12 In comparison to In 2 O 3 , indium oxide clusters (InOCs) provide clear structural information and allow for atomic-level control of cluster size.…”
