This application relates to the field of nanophotocatalytic materials technology, and discloses a conjugated polyelectrolyte / mesoporous nano-titanium dioxide composite photocatalyst, its preparation method, and its application. The preparation method includes: dissolving Pluronic F127 in tetrahydrofuran to obtain a homogeneous solution; adding glacial acetic acid and hydrochloric acid to the solution and stirring until homogeneous to obtain a precursor solution; rapidly adding tetrabutyl titanate to the precursor solution and stirring until homogeneous; then removing the solvent and crystallizing in situ; collecting the solid phase and calcining it to obtain mesoporous titanium dioxide; dispersing the conjugated polyelectrolyte (CPEs) in a solvent, then adding the mesoporous titanium dioxide for self-assembly, removing the solvent, and obtaining the composite photocatalyst. The composite photocatalyst prepared in this application exhibits a wider visible light response range and superior photocatalytic water splitting for hydrogen production. It can fully utilize the photosensitization and charge transport advantages of CPEs under extremely low loading conditions, achieving excellent photocatalytic hydrogen production performance without the need for noble metal co-catalysts.

The invention relates to the technical field of carbon nanotubes, in particular to an enrichment method of a single-chiral single-walled carbon nanotube based on conjugated polyelectrolyte. The enrichment method of the single-chiral single-walled carbon nanotubes based on the conjugated polyelectrolyte is low in cost, efficient and high in purity, the conjugated polyelectrolyte on the surface is convenient to remove, and mass enrichment of the single-chiral single-walled carbon nanotubes not coated with a dispersing agent is truly achieved.
