Abstract

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.
