Enhancing photocatalytic activity of C60-based photocatalyst for visible-light-driven hydrogen evolution with the coupling of Fe3O4 microbead to modulate charge separation efficiency
Interfacial charge separation is an essential issue to restrict catalytic activity of photocatalysts. In this work, we report a promising and easy-to-handle strategy to modulate the activity of a C60-based photocatalyst (C60@Pt) for visible-light-driven hydrogen evolution reaction (HER) with the cou...

| Summary: | Interfacial charge separation is an essential issue to restrict catalytic activity of photocatalysts. In this work, we report a promising and easy-to-handle strategy to modulate the activity of a C60-based photocatalyst (C60@Pt) for visible-light-driven hydrogen evolution reaction (HER) with the coupling of magnetic substance that had weak ferromagnetism (Fe3O4 microbeads as an instance). It is found that Fe3O4 microbeads played a pivotal role in boosting photocatalytic activity and apparent quantum efficiency of C60@Pt for visible-light-driven HER, as the weak local magnetic field it induced around C60@Pt contributed to facilitating the separation of photo electrons from electron-donor in reaction system. |
