Direct Z-scheme WO3- nanowire-bridged TiO2 nanorod arrays for highly efficient photoelectrochemical overall water splitting

Gas-phase photoelectrocatalytic oxidation of volatile organic compounds using defective WO3/TiO2 nanotubes mesh

“…The signal declined upon the loading of WO 3 nanoparticles due to a built-in electric field developed by bending of the contact interfacial energy band between TiO 2 and WO 3 . 33,34 Further diminishing of the PL signal was observed upon the introduction of defects, indicating that the recombination of the photogenerated carriers was inhibited due to the defects. Notably, in comparison with pristine WO 3 /TNTs, the PL signal for the defective R-WO 3 /TNTs was evidently quenched with the external bias, as the recombination was inhibited by the much more rapid carrier transfer.…”

Controllable synthesis of Co nanoparticles with the assistance of cucurbit[6]uril and its efficient photoelectrochemical catalysis in water splitting on a g-C3N4 photoanode

“…The incident photon-to-current conversion efficiency (IPCE) measurements of the as-prepared photoanodes were performed at various incident light wavelengths. [37][38][39] In Fig. 5b, the IPCE of the g-C 3 N 4 /Q[6]-Co NPs was much better than that of g-C 3 N 4 in the visible light region, which was attributed to the formed semiconductor-metal junction at the g-C 3 N 4 /Q[6]-Co NP interface, providing more reaction sites and efficient charge carrier transport channels to capture light and excited electrons.…”

Addressable Label-Free Photoelectric Sensor Array with Self-Calibration for Detection of Neuron Specific Enolase

“…Many researchers prefer TiO 2 nanorod arrays produced on FTO in situ because of their high order, large specific surface area, and higher adsorption capacity. − However, TiO 2 has a wide band gap, making it susceptible to carrier recombination and the absorption and use of visible light is limited. Thus, it is required to combine with narrow-band semiconductors to reform the usage of visible light and decrease carrier recombination.…”
