An Efficient Bias‐Free Si Photocathode Coupled BiVO4‐Triethanolamine Photoelectrochemical Fuel Cell for Simultaneous Pollutant Treatment and Hydrogen Production

“…In addition to the typical Bi-O and V-O stretching vibration peaks of BiVO 4 , the C-O and C-N stretching vibration peaks corresponding to TEOA also appear in the FTIR spectrum of the O V :BiVO 4 photoanode after the PEC test. [37,38] Moreover, the aforementioned Bi-O and V-O, and C-O, and C-N stretching vibration peaks exhibit notable negative shifts as compared to those of the pristine O V :BiVO 4 photoanode and TEOA, respectively, indicating the existence of a robust complexation (chemical adsorption) between the O V :BiVO All the above results demonstrate the presence of a robust complexation between the O V :BiVO 4 photoanode and TEOA. To probe and verify the importance of the strong complexation for the outstanding PEC performance, a thin TiO 2 film was deposited on the O V :BiVO 4 photoanode using an atomic layer deposition (ALD) technology to isolate direct contact between the O V :BiVO 4 photoanode and TEOA.…”

“…In addition to the typical Bi–O and V–O stretching vibration peaks of BiVO 4 , the C–O and C–N stretching vibration peaks corresponding to TEOA also appear in the FTIR spectrum of the O V :BiVO 4 photoanode after the PEC test. [ 37,38 ] Moreover, the aforementioned Bi–O and V–O, and C–O, and C–N stretching vibration peaks exhibit notable negative shifts as compared to those of the pristine O V :BiVO 4 photoanode and TEOA, respectively, indicating the existence of a robust complexation (chemical adsorption) between the O V :BiVO 4 photoanode and TEOA. The XPS measurements (Figure S10, Supporting Information) reveal that the binding energies of Bi and V in the O V :BiVO 4 photoanode after the PEC test all shift to lower values relative to those of the pristine O V :BiVO 4 photoanode, which further indicates the existence of a robust complexation between the O V :BiVO 4 photoanode and TEOA and the enhanced charge density on the O V :BiVO 4 photoanode after the PEC test.…”
