An efficient photoelectrochemical cell for water splitting based on tetrapod‐shaped CdS nanocrystals is reported by H. Zhang and co‐workers on page 4727. The tetrapod‐shaped CdS nanocrystals with tunable arm lengths and diameters are synthesized via a facile, phosphine‐free, solution‐based chemical method. Introducing tetrapod‐shaped CdS nanocrystals with longer arm lengths provides less branch connection points/junctions, which probably trap and block the transportation of photoexcited electrons/holes, resulting in promising photocatalytic activity for water splitting in photoelectrochemical cells.
