Abstract
The effect of doping of the Zn x Cd 1− x S ( x = 0.37–0.50) alloy nanocrystals with Mn 2+ ions on the rate and apparent quantum yield of the photocatalytic H 2 evolution catalyzed by this alloy has been investigated. It has been found that the ZnS shell significantly increases the lifetime of the Mn 2+ excited state, which leads to the generation of ‘hot’ electrons and the two-photon photocatalytic reduction of hydrogen ions. An analysis of the characteristics of nanocrystals without a ZnS shell with similar excitation energies of the edge exciton revealed that the efficiency of the alloy doped with Mn 2+ ions is 1.2–1.3 times higher due to an increase in the lifetime of photoinduced electron–hole pairs.
