Spin-selection in L-chiral Ag-doped WS 2 nanoflower for photocatalysis

In this study, we synthesized a novel heterostructure comprising two-dimensional tungsten sulfide nanoflowers and chiral silver nanoparticles. Leveraging the chiral-induced spin selection (CISS) effect, our WS2@L-His/Ag(chiral) system achieved a remarkable 77% enhancement in photocatalytic degradation efficiency over the WS2@Ag(achiral) counterpart. The chiral nanostructures selectively facilitate the transport of electrons with defined spin orientations, thereby suppressing the recombination of
