A p-n Junction by Coupling Amine-Enriched Brookite-TiO Nanorods with CuS Nanoparticles for Improved Photocatalytic CO Reduction.

Photocatalytic CO reduction is a promising technology for reaching the aim of "carbon peaking and carbon neutrality", and it is crucial to design efficient photocatalysts with a rational surface and interface tailoring.
