Assembly-promoted photocatalysis: Three-dimensional assembly of CdSxSe1−x (x = 0-1) quantum dots into nanospheres with enhanced photocatalytic performance

CdSxSe1−xassembled nanospheres were fabricated from CdSxSe1−x quantum dots (x = 0-1) via a emulsion-based bottom-up self-assembly approach. The unique architecures of the self-assembled CdSxSe1−x QDs resulted in enhanced light harvesting and facilitated the photoinduced electron-hole separation, which made a good contribution to their improved performance in photocatalytic hydrogen evolution from water.191
