A photocatalyst with an enhanced Schottky effect and an efficient electron-transfer channel fabricated by assembling Ni–WC heterojunction nanoparticles on g-C₃N₄ for highly efficient removal of chlorophenols

Abstract

Fabricating photocatalysts with optimized charge kinetics to improve carrier transfer and separation is critical for the removal of highly-toxic chlorophenols pollutants. Herein, a Mott-Schottky catalyst constructed by assembling nickel-tungsten carbide...

Progress on enhancing the charge separation efficiency of carbon nitride for robust photocatalytic H2 production

“…Meanwhile, the rectification characteristic of the Schottky barrier suppresses the back recombination of charge carriers, ensuring the directional charge transfer and improving charge separation efficiency. 147,148 Therefore, a perfect match of g-C 3 N 4 and cocatalyst and the appropriate Schottky barrier are necessary to facilitate the interfacial charge transfer, prolong the lifetime of charge carriers, and improve photocatalytic H 2 production activity.…”
