文摘
- •
Zinc oxide-deposited carbon spheres were in situ synthesized by a thermolysis method.
- •
They exhibited a strong light absorption band across the whole visible range.
- •
They showed a very high electrical conductivity (∼1300 S/m).
- •
They acted as excellent photocatalysts for the decomposition of methylene blue.
- •
Covalent bonding between the core and outer layer led to an increased lifetime of charge carriers.
