Micro-arc oxidation of TC4 substrates to fabricate TiO2/YAG:Ce3+ compound films with enhanced photocatalytic activity

“In situ” preparation of a TiO2/Eu2O3 composite film upon Ti alloy substrate by micro-arc oxidation and its photo-catalytic property

“…The half-value width of the anatase (1 0 1) peak (FWHM) was 0.24, while the TiO 2 /Eu 2 O 3 was 0.28, which revealed that the diameter of the grain size in the TiO 2 /Eu 2 O 3 composite film was smaller than that of pristine TiO 2 film. Similar results were also obtained in our previous work [12]. This was because that Eu 2 O 3 acted as nuclear sites or assistant nuclear sites for TiO 2 growth during MAO process.…”

“…And it provides a powerful technique to in situ prepare a high quality TiO 2 film with high micro-hardness, high adhesion, high strength and high wear resistance upon the surface of Ti substrates, which has been used in various areas, such as photocatalysts, sensors and solar cells, etc. [12][13][14][15].…”

Marginally Hydrogenated Triphasic Titania Nanotubes for Effective Visible‐Light Photocatalytic Hydrogen Generation

“…The synthesis of black‐colored titania requires either high‐pressure hydrogenation or high‐temperature hydrogenation, as reported in the literature. In our case, black titania was not obtained under the present hydrogenation conditions, even with a prolonged annealing time (7 h at temperatures of 250 and 450 °C).…”

“…Moreover, the titania surface has been modified by various means such as coupling with a narrow band gap semiconductor, plasmonic metals, and so on to reduce the recombination of photogenerated charge carriers. Among the modifications adopted, introducing phase junctions was proven to be an effective strategy to inhibit the fast recombination of excited charge carriers .…”

A strategy for single-step elaboration of V2O5-grafted TiO2 nanostructured photocatalysts with evenly distributed pores

“…MAO can be expressed as a valid process for "in situ" preparing of ceramic coatings. In the case of TiO 2 , the phase structure can be controlled by adjusting the experimental conditions [23]. The details of the MAO process can be found elsewhere [24][25][26].…”
