Pt‐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 کاملVisible Light-Driven Photocatalytic Performance of N-Doped ZnO/g-C3N4 Nanocomposites
N-doped ZnO/g-C3N4 composites have been successfully prepared via a facile and cost-effective sol-gel method. The nanocomposites were systematically characterized by XRD, FE-SEM, HRTEM, FT-IR, XPS, and UV-vis DRS. The results indicated that compared with the pure N-doped ZnO, the absorption edge of binary N-doped ZnO/g-C3N4 shifted to a lower energy with increasing the visible-light absorption ...
متن کاملEfficient photocatalytic hydrogen evolution over hydrogenated ZnO nanorod arrays.
Hydrogenated ZnO nanorod arrays (NRAs) grown on F-doped SnO(2) (FTO) glass substrates yield a benchmark specific hydrogen production rate of 122,500 μmol h(-1) g(-1), and exhibit excellent stability and recyclability.
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 کاملPreparation and enhanced visible light photocatalytic activity of novel g-C3N4 nanosheets loaded with Ag2CO3 nanoparticles.
As a potential visible-light photocatalyst, the photocatalytic performance of the bulk g-C3N4 synthesized by heating melamine (denote as g-C3N4-M) is limited due to its low specific surface area and the high recombination rate of the photo-induced electron-hole pair. In this paper, a novel g-C3N4-M nanosheet (g-C3N4-MN) obtained from the bulk g-C3N4-M through a thermal exploitation method is em...
