Construction of ternary CdxMo1−xSe quantum dots for enhanced photocatalytic hydrogen production
Source abstract
Abstract
The development of novel photocatalyst is an important issue for improving the photocatalytic hydrogen production efficiency. Herein, novel aqueous ternary CdxMo1−xSe quantum dots (QDs) are prepared with five ratios (x = 0, 0.5, 0.67, 0.75, 1) by modulating the metal content. Experimental results show that the doping of Mo promotes the photoinduced electrons transfer and decreases the photoinduced electron–hole pairs recombination. Compared with the CdSe QDs, Cd0.75Mo0.25Se QDs, Cd0.5Mo0.5Se QDs and MoSe2 QDs, Cd0.67Mo0.33Se QDs exhibit significantly enhanced photocatalytic activity, and the amount of H2 production comes up to 911.1 μmol in 7 h. Meanwhile, the Cd0.67Mo0.33Se QDs display substantially high stability in recycling test, which facilitates the utilization of ternary QDs in the photocatalytic hydrogen production application.
