BiOBr/Bi5O7I/TiO2/Ti Photoanode Assembled Visible Light Responsive Photocatalytic Fuel Cell for Efficient Rhodamine B Degradation and Stable Electricity Generation

“…The VB and CB of the photocatalyst is a crucial factor in charge transfer and formation of heterojunctions. [40,41] Based on equations 2 and 3, [42] the potentials of the CB and VB of TiO 2 are À 0.23 and 2.85 eV, respectively. In addition, according to previous reports, [15,27] the potentials of the CB and VB of BiOBr are À 0.50 and 2.18 eV, respectively, and the corresponding values of Bi 5 O 7 I are À 0.69 and 1.56 eV, respectively.…”

“…Where χ (5.81 eV), [42] Ee (4.5 eV) [43] and Eg (eV) represent electronegativity of the semiconductor, energy of free electrons on the hydrogen scale and the band gap of the semiconductor, respectively.…”

Construction of organic–inorganic hybrid photoanodes with metal phthalocyanine complexes to improve photoelectrochemical water splitting performance

“…3c, the peak at 529.6 eV corresponds to the lattice oxygen of BVO, while the peak at 531.8 eV represents the existence of –OH groups. 38,39 Compared with the O 1s spectrum of the BVO photoanode, the relative peak intensity of lattice oxygen is decreased, which may be related to the CoPc covered on the surface. For the C 1s spectrum in Fig.…”
