New effects of TiO2 nanotube/g-C3N4 hybrids on the corrosion protection performance of epoxy coatings

Fabrication and characterization of a TiBs@MCN cable-like photocatalyst with high photocatalytic performance under visible light irradiation

“…The strength of the peak at 12.7°, reflecting the regular arrangement of triazine rings in the g-C 3 N 4 plane, is weaker compared with the peak at 27.5° corresponding to the typical graphite interlaminar stacking structure. 18,49 The peak at 27.5° is much more evident in MCN lamellas than that in bulk g-C 3 N 4 because of the small crystallite size of MCN. Meanwhile, the peak at 12.7° (100) in MCN almost disappears, indicating the successful stripping of g-C 3 N 4 nanosheets.…”

“…Many strategies have been proposed to improve the visible-light photocatalytic efficiency of TiO 2 such as ion doping materials, metal loading materials, heterojunction hybrids, and sensitization. 14–18 Among them, heterojunction formation with the use of narrow bandgap semiconductors is considered to be one of the most effective methods to address the above-described limitations of TiO 2 . 19…”

[14][15][16][17][18] Among them, heterojunction formation with the use of narrow bandgap semiconductors is considered to be one of the most effective methods to address the abovedescribed limitations of TiO 2 . 19 On other hand, graphite carbon nitride (g-C 3 N 4 ), as an n-type semiconductor, has attracted remarkable attention because of its good visible light photocatalytic performance and high photocatalytic stability with a narrow band gap of about 2.7 eV.…”

Photocatalytic concrete for degrading organic dyes in water

“…Chemical studies have proved that g-C 3 N 4 is completely nontoxic and chemically stable (Tang et al 2019;He et al 2020). Moreover, g-C 3 N 4 has strong acid and alkali corrosion resistance, which makes g-C 3 N 4 suitable for concrete structures susceptible to corrosion (Pourhashem et al 2020). In addition to the advantages of g-C 3 N 4 as photocatalysts above, g-C 3 N 4 is easy to be modified to be more active by morphology control, semiconductor recombination, element doping, and molecular doping (Liu et al 2019a, b).…”

Improved Anticorrosion Properties of Polyurethane Nanocomposites by Ti3C2Tx MXene/Functionalized Carbon Nanotubes for Corrosion Protection Coatings

“…Over the past decades, two-dimensional (2D) nanomaterials have gained the most attention due to their large aspect ratio that can provide the maximum physical barrier effect . Commonly utilized 2D materials for anticorrosion applications include but are not limited to graphene and graphene oxide, , hexagonal boron nitride, molybdenum disulfide, graphitic carbon nitride, the MXene family, etc. Recently, MXene as an emerging material has attracted increasing interest among the scientific community due to its optical, electrical, mechanical, and electrochemical properties .…”
