Abstract: The highest rate of CO₂ reduction over 5 wt% Ti₃C₂(F)/TiO₂ photocatalyst under visible light at variable reaction temperature was achieved at 50 °C. Strong deactivation of the photocatalyst during CO₂ reduction has been caused by the amorphization of 2D-structured MXene layers.

Keywords: photocatalysis, CO₂ reduction, visible light, g-C₃N₄, MXene.
