Efficient and Stable MoOX@Mo-BiVO4 Photoanodes for Photoelectrochemical Water Oxidation: Optimization and Understanding

“…TOF-SIMS of the MoO X @2% Mo-BiVO 4 photoanode was used to acquire the details of the depth, surface, and interface of the electrodes. , Figure a presents the TOF-SIMS spectra of the BiVO 4 + , V + , VO – , Mo + , MoO 3 – , and O – ions as functions of sputtering time. The results clearly indicate that a certain amount of (NH 4 ) 6 Mo 7 O 24 ·4H 2 O as a source of Mo doping in the precursor was converted into MoO X after the calcination process.…”

“…TOF-SIMS of the MoO X @2% Mo-BiVO 4 photoanode was used to acquire the details of the depth, surface, and interface of the electrodes. 31,32 Figure 2a presents the TOF-SIMS O as a source of Mo doping in the precursor was converted into MoO X after the calcination process. This indicates that MoO X was welldistributed in the MoO X @2% Mo-BiVO 4 films.…”

Improving Photoelectrochemical Activity of Magnetron-Sputtered Double-Layer Tungsten Trioxide Photoanodes by Irradiation with Intense Pulsed Ion Beams

“…The proper band alignment of photoanode layers with water oxidation potentials opens a route to significantly increasing photocurrent generation because of the better charge separation in multiple-layered heterostructures. Additionally, the PEC performance of photoelectrodes can be boosted by combining 2D materials with WO 3 [ 31 , 32 ], controlling the texturing of particular crystallographic facets [ 33 , 34 , 35 ], creating unassisted tandem cell structures [ 36 ], using plasmonic nanoparticles [ 37 ], and by creating oxygen vacancies [ 38 ].…”
