Plasmonic Zn0.5Cd0.5S/NaxMoO3 composites with excellent full-spectrum driven photocatalytic hydrogen activity

Developing the full-spectrum driven photocatalysts is considered as a potential strategy to realize the high-efficient photocatalytic hydrogen. Herein, plasmonic Na x MoO 3 with oxygen vacancies was coupled with Zn 0.5 Cd 0.5 S to construct Z-scheme heterostructure . The Zn 0.5 Cd 0.5 S /Na x MoO 3 photocatalysts perform UV–vis-NIR-driven extraordinary photocatalytic hydrogen activity: the H 2 rates of Zn 0.5 Cd 0.5 S/Na x MoO 3 -5 under the irradiation of full-spectrum, > 420 nm, > 520 nm and > 780 nm are 6033, 2846, 92, 54 μmolg -1 h −1 , respectively, showing an energy distribution that eligible the distribution of solar energy. Benefiting from the synergistic impact of the interfacial Z-type heterojunction and the tunable plasmonic resonance of Na x MoO 3 , the composites shows excellent full-spectrum absorption and the high charge separation efficiency. This work endows Zn 0.5 Cd 0.5 S the NIR-driven photocatalytic H 2 ability by utilizing the LSPR effect of Na x MoO 3 , which provides a new horizon to realize the high-efficient photocatalytic performance and the sufficient usage of solar light.
