| abstract |
The invention discloses a carbon-doped tin disulfide (C-SnS 2 ) and other SnS 2 composites, the carbon-doped tin disulfide (C-SnS 2 ) and other SnS 2 composites are used for reducing CO 2 . A visible light photocatalyst that becomes a solar fuel. The in situ carbon-doped SnS 2 photocatalyst has higher efficiency than the undoped pure SnS 2 . The invention also discloses a process for preparing the catalyst. |
