An S-scheme α-Fe2O3/g-C3N4 heterojunction nanostructure with superior visible-light photocatalytic activity for the aza-Henry reaction

A S-scheme α-Fe 2 O 3 /g-C 3 N 4 composite was designed and fabricated. The α-Fe 2 O 3 /g-C 3 N 4 showed improved photocatalytic activity for Aza-Henry reaction. S-scheme mode of charge transfer in composite enhanced the catalytic performance.
