The different roles of introduced sulfide ions (S2−) on the surface of CdSe quantum dots are revealed by Li‐Zhu Wu and co‐workers in article number 1804872. At an earlier stage, S2− grows into the lattice and accelerates electron transfer, while afterward, the S2− works as ligands and promotes hole transfer, thus greatly improving the efficiency of quantum dots for photocatalytic hydrogen evolution...
Semiconducting quantum dots (QDs) have recently triggered a huge interest in constructing efficient hydrogen production systems. It is well established that a large fraction of surface atoms of QDs need ligands to stabilize and avoid them from aggregating. However, the influence of the surface property of QDs on photocatalysis is rather elusive. Here, the surface regulation of CdSe QDs is investigated...
