Scholarcy highlights

  • O2− played the predominant role while OH was the secondary one for the photodegradation of gaseous acetaldehyde
  • The introduction of reduced graphene oxide led to superior adsorptive property while harmful change of active radicals
  • It was found that RGOP had increased absorbance, it possessed lower available light utilization compared with P25
  • In comparison to P25, the change of active radicals of RGOP was adverse to its photocatalysis
  • The improved photocatalytic activity of RGOP was ascribed to its superior adsorptive ability aside from active radicals
  • New insights into reduced graphene oxide/P25 composite and its photocatalytic performance
