Resumen

The construction of a 2D–2D heterostructured composite is an efficient method to improve the photocatalytic hydrogen generation capability under visible light. In this work, simple heat treatment of a mixture of g-C ₃ N ₄ and delaminated Ti ₃ C ₂ was used to prepare a series of d-Ti ₃ C ₂ /TiO ₂ /g-C ₃ N ₄ nanocomposites. The d-Ti ₃ C ₂ not only acted as the support layer and resource to glue the anatase TiO ₂ particles and g-C ₃ N ₄ layers together but also served as the fast electron transfer channel to improve the photogenerated charge carriers’ separation efficiency. By tuning the g-C ₃ N ₄ /d-Ti ₃ C ₂ mass ratio, heating temperature and soaking time, the d-Ti ₃ C ₂ /TiO ₂ /g-C ₃ N ₄ nanocomposite 4-1-350-1 achieved an excellent H ₂ evolution rate of 1.62 mmol h ⁻¹ g ⁻¹ driven by a 300 W Xe lamp with a 420 nm cutoff filter. The heterostructured composite photocatalyst was stable even after 3 cycles, representing excellent potential for the practical application in solar energy conversion.
