CO2 Photoreduction Under Visible Light by TiO2 and Carbon Dots Derived from Pyrolized Bio-Oil.

Herein, we report a study on pyrolysis bio-oil upgrading from leather shaving waste to dope in situ titania (TiO2) with carbon dots (cds). The cds doped TiO2 exhibits remarkable activity as photocatalyst under solar light for the direct conversion of carbon dioxide (CO2) and water vapor (H2O) to methane (CH4). Morover, the catalytic activity also increased under uv radiation.
