Synthesis of Ag or Pt nanoparticle-deposited TiO2 nanorods for the highly efficient photoreduction of CO2 to CH4

Highlight
- Ag or Pt-deposited TiO2 nanocomposites (<20 nm) were prepared by a simple method.
- The modified catalysts exhibited extremely high CO2 photoreduction efficiency.
- The maximum CH4 yield rated up to 16.0 ppm/g h.
