Surface stoichiometry is a sensitive parameter affecting the decay dynamics of photogenerated hole-electron pairs of QDs. However, the effect of this manipulation on artificial photocatalytic H 2 evolution is unclear. Here, we report that surface stoichiometry manipulation is a facile and feasible a...
