Electrochemically Deposited Cu2O-Doped TiO2 Nanotube Photoanodes for Hydrogen Evolution

Combination of alkali treatment and Ag3PO4 loading effectively improves the photocatalytic activity of TiO2 nanoflowers

“…It can be seen that there are two characteristic peaks at 530.87 eV and 529.54 eV corresponding to the Ti-OH and Ti-O bonds, respectively. [39][40][41] Fig. 4c shows the O 1s spectrum of Ag 3 PO 4 /OH/TiO 2 ; compared to the O 1s spectrum of TiO 2 , two new characteristic peaks appeared at 531.02 eV and 532.93 eV, corresponding to P-O and Ti-O-Ag bonds, which are caused by the loading of Ag 3 PO 4 .…”

Fabrication of Cu2O-loaded TiO2 nanotubes with heterojunctions via an electrochemical method: enhanced photocatalytic activity

“…5), which may due to the adsorption desorption reaction mechanism during the photodegradation process on the Cu 2 O–TiO 2 NT surface, which is consistent with our previous work. 1,27 Fig. 6(b) shows the incident photon-to-electron conversion efficiency (IPCE) under monochromatic illumination, which was calculated using the following formula:where j p is the photocurrent density, P is the incident light density per unit area, and λ is the incident light wavelength.…”

“…The energy shortage crisis and environmental pollution caused by fossil fuels are critical issues that need to be resolved urgently to achieve sustainable development. 1–6 Photocatalytic technologies are considered to be effective methods for overcoming these issues, because clean hydrogen energy can be obtained via water splitting on a photoanode under solar irradiation. 7–10 In the early 1970s, Honda and Fujishima reported hydrogen production on a TiO 2 electrode under UV-light irradiation.…”

Synthesis of hollow sphere structured TiO2 loaded with Ag2O and its photocatalytic activity

“…Although TiO 2 has attracted significant attention for its application as a photocatalyst in water decomposition owing to its high catalytic activity, excellent stability, and its nontoxicity, [1][2][3] the rapid recombination of charge carriers and short-wavelength excitations have hindered its practical applications. [4][5][6] Similar to most semiconductor materials, the high recombination rates between the electrons and holes in TiO 2 generate low quantum yields.…”
