متن کاملPt‐Decorated g‐C3N4/TiO2 Nanotube Arrays with Enhanced Visible‐Light Photocatalytic Activity for H2 Evolution
Aligned TiO2 nanotube layers (TiNTs) grown by self-organizing anodization of a Ti-substrate in a fluoride-based electrolyte were decorated with graphitic-phase C3N4 (g-C3N4) via a facile chemical vapor deposition approach. In comparison with classical TiO2 nanotubes (anatase), the g-C3N4/TiNTs show an onset of the photocurrent at 2.4 eV (vs. 3.2 eV for anatase) with a considerably high photocur...
متن کاملThe facile synthesis of mesoporous g-C3N4 with highly enhanced photocatalytic H2 evolution performance.
Mesoporous g-C3N4 has been obtained by a facile sucrose-mediated approach via thermal condensation of sucrose and melamine for the first time. The mesoporous g-C3N4 presents a much higher BET surface area and displays highly enhanced photocatalytic H2 evolution performance.
متن کاملEnhanced Photocatalytic Performance of Luminescent g-C3N4 Photocatalyst in Darkroom.
Graphitic-C3N4(g-C3N4), a low-cost visible-light-driven photocatalyst, was used for the photocatalytic oxidation of aqueous methylene blue (MB) in the dark with Sr4Al14O25:(Eu,Dy) assistance. The Sr4Al14O25:(Eu,Dy)/g-C3N4 photocatalysts were fabricated through the ultrasonic dispersion method. The commercial Sr4Al14O25:(Eu,Dy) phosphor was used as a long afterglow supplier for exciting g-C3N4 i...
متن کاملPhotocatalytic Properties of g-C3N4–TiO2 Heterojunctions under UV and Visible Light Conditions
Graphitic carbon nitride (g-C₃N₄) and titanium dioxide (TiO₂) were chosen as a model system to investigate photocatalytic abilities of heterojunction system under UV and visible light conditions. The use of g-C₃N₄ has been shown to be effective in the reduction in recombination through the interaction between the two interfaces of TiO₂ and g-C₃N₄. A simple method of preparing g-C₃N₄ through the...
