AI Technical Summary
Existing TiO2 nanomaterials have poor absorption of visible light and low separation efficiency of photogenerated carriers, resulting in low solar energy utilization and photogenerated electron utilization.
A porous rutile TiO2 nanomaterial was constructed by pyrolyzing a high specific surface area titanium-based MOF framework under an inert atmosphere and achieving in-situ rearrangement and directional phase transformation of titanium-oxygen clusters through a topological confinement pyrolysis strategy. Single-atom Cu and Pt-Cu alloys were then loaded onto the nanomaterial to construct a heterojunction to optimize electron transport channels.
It improves the material's response to visible light and photocatalytic performance, exhibits good adsorption and photocatalytic degradation effects on Rhodamine B, enhances the spatial separation efficiency of photogenerated carriers, and improves photocatalytic reaction activity.
