Abstract

This study communicates an investigation on the facile combination of Ti₃C₂ MXene nanosheet and TiO₂ as an efficient catalyst for the photoreduction of bicarbonate to produce formic acid. Ti₃C₂ has a distinct two-dimensional structure with a nanoscale thickness. Ti₃C₂ could well interact and envelop the TiO₂ particles and decrease the bandgap of the composite. As a result, a bandgap of 2.9 eV, located in the visible light region, could be achieved. The catalytic tests show that Ti₃C₂/TiO₂ composite could produce formic acid up to 7.5 mmol g.cat⁻¹, ∼2.5 times higher than pristine TiO₂.
