From: NiFe Prussian blue analog cocatalyzed TiO2/In2S3 type-II heterojunction for solar water splitting
Figure 2. (A) XRD patterns of TiO2, TiO2/In2S3, and TiO2/In2S3/NFP. XPS spectra of (B) Ti 2p, (C) O 1s, and (D) S 2p of TiO2/In2S3. XPS spectra of (E) C 1s, (F) N 1s, (G) Ni 2p, and (H) Fe 2p of TiO2/In2S3/NFP. Inset of (F): the crystal structure of NiFe PBA. (I) Transmission spectra and UV-vis absorption spectra of TiO2 and TiO2/In2S3 with the different concentrations of indium nitrate in the precursor.
