LaFeO3 meets nitrogen-doped graphene functionalized with ultralow Pt loading in an impactful Z-scheme platform for photocatalytic hydrogen evolution

Under visible-light irradiation, ternary LaFeO 3 @NGr–Pt NPs Z-scheme delivered a PHE performance (3.52 μmol mg cat −1 h −1 ) superior to binary LaFeO 3 @NGr (1.86 μmol mg cat −1 h −1 ), NGr–Pt NPs (0.88 μmol mg cat −1 h −1 ), and NGr (0.34 μmol mg cat −1 h −1 ).
