Ion‐Exchange Synthesis of ZnO/ZnSe/CdSe Core/Shell Heterostructured Nanowire Photoanodes toward High‐Performance Photocathodic Protection of 304 Stainless Steel

“…Construction of heterostructured semiconductor systems with well-matched band energies offers new opportunities to enhance spatial charge separations and ultimately boost photoelectrochemical properties. [8] Recently, various narrow bandgap semiconductors capable of absorbing visible light of solar spectrum have been composited with TiO 2 and ZnO to form heterojunctions for improving PCP performances, such as In 2 S 3 , [4] CdS, [9] Bi 2 S 3, [10] Sb 2 S 3 , [11] ZnIn 2 S 4 , [12] AgInSe 2 , [13] BiVO 4 , [14] TpBD-COF, [15] MoS 2 , [16] FeS 2 , [17] etc. In the meanwhile, geometric advantages of nanowire arrays over planar films have been demonstrated in the photoelectrochemical fields.…”

Preparation of SnIn4S8/TiO2 Nanotube Photoanode and Its Photocathodic Protection for Q235 Carbon Steel Under Visible Light

“…This indicated that Ti 4+ existed in the SnIn 4 S 8 /TiO 2 composite. Figure 5 c shows the peaks at 529.7 and 531.6 eV, which correspond to lattice oxygen and adsorbed oxygen, respectively [ 46 ]. The lattice oxygen represented the Ti–O, indicating the existence of TiO 2 in the composite.…”

The investigation of CdS-quantum-dot-sensitized Ag-deposited TiO2 NRAs in photoelectrochemical hydrogen production

“…Nevertheless, it is possible to shift the solar light absorption of TiO 2 from the UV to visible spectrum by combining it with visible light absorbers including BiVO 4 , 10,11 Fe 2 O 3 , 12,13 WO 3 , 14,15 and CdS. [16][17][18][19][20] CdS is an n-type semiconductor, which combines with TiO 2 photoanode materials to generate a heterostructure, reducing recombination of the photo-induced electron-hole pairs. CdS acts as a visible-region absorber in the heterostructure and electrons are photo-induced on the CdS surface in the visible region owing to the bandgap of CdS being about B2.4 eV lower transfer to the TiO 2 nanostructure.…”
