Abstract: The modification of TiO2-based photocatalysts with 5 wt% Ti3C2 (MXene) enhanced the reaction rate of CO2 reduction by a factor of 2.8. The MXene Ti3C2 is an effective cocatalyst for CO2 reduction to CH4 under visible light irradiation (400 nm).

Keywords: photocatalysis, photocatalysts, MXenes, titanium carbide, Ti3C2, titanium dioxide, TiO2, photocatalytic CO2 reduction.
