Enhancement of photocatalytic H2 evolution from water splitting by construction of two dimensional gC3N4/NiAl layered double hydroxides
Source abstract
Abstract
Abstract Photocatalytic water splitting is a direct and potential approach to generate hydrogen (H2), but it is very difficult to find the ideal semiconducting materials with maximum photocatalytic water splitting efficiency. Herein, we synthesized 2D/2D heterojunction of NiAl-LDH/gC3N4 nanocomposite by in situ hydrothermal method and demonstrated their photocatalytic performance for H2 evolution from water splitting under simulated light irradiation. The optimized NiAl-LDH/gC3N4 nanocomposites showed the H2 evolution rate of 3170 µmol h−1 g−1, the highest value so far reported for NiAl-LDH family. The enhanced photocatalytic efficiency is attributed to the formation of 2D/2D heterojunction in NiAL-LDH/gC3N4 nanocomposite, leading to excellent electron-hole separation under light illumination, which increases the electron conductivity in the composite. Present work provides the new insights for the design of layered double hydroxides based 2D/2D heterojunction as a high-performance photocatalyst for H2 evolution from water splitting.
