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

An enhanced Schottky effect and efficient electron-transfer channel in Ni–WC/CN enable the efficient separation and transfer of photoexcited electrons, which boosts efficient photocatalytic degradation of toxic 4-chlorophenol.
