Encapsulated CdSe/CdS nanorods in double-shelled porous nanocomposites for efficient photocatalytic CO₂ reduction.

ABSTRACT: Colloidal quantum dots have been emerging as promising photocatalysts to convert CO₂ into fuels by using solar energy. However, the above photocatalysts usually suffer from low CO₂ adsorption capacity because of their nonporous structures, which principally reduces their catalytic efficiency. Here, we show that synchronizing imine polycondensation reaction to self-assembly of colloidal CdSe/CdS nanorods can produce micro-meso hierarchically porous nanocomposites with double-shelled nanocomposites. Owing to their hierarchical pores and the ability to separate photoexcited electrons, the self-assembled porous nanocomposites exhibit remarkably higher activity (≈ 64.6 μmol g^-1 h^-1) toward CO₂ to CO in solid-gas regime than that of nonporou
