Quasi-noble-metal graphene quantum dots deposited stannic oxide with oxygen vacancies: Synthesis and enhanced photocatalytic properties

The nanocomposite photocatalysts of quasi-noble-metal graphene quantum dots (GQDs) deposited SnO2 with oxygen vacancies (VOs) were prepared through a simple two-step reactions process. The obtained nanocomposites exhibited much enhanced photodegradation activity for the extended visible-light response as well as raised charge-separation efficiency.91
