Fullerene [C60] modified Cr2−xFexO3 nanocomposites for enhanced photocatalytic activity under visible light irradiation

C 60 modified Cr 2− x Fe x O 3 nanostructure photocatalysts were successfully synthesized by a simple absorbing process and employed in the photocatalytic H 2 evolution. The as-prepared C 60 –Cr 2− x Fe x O 3 nanocomposites exhibits significantly enhanced photocatalytic activity for photocatalytic H 2 evolution without any noble metal. It is shown that the photoinduced electrons achieve high migration efficiency on the interface C 60 and Cr 2− x Fe x O 3 , which is generated by the intense interaction of C 60 and Cr 2− x Fe x O 3 with conjugative three-dimensional π-system. A possible mechanism was proposed and supported by the PL emission spectrum technique and transient photocurrent responses.
