Application of QD-MOF composites for photocatalysis: Energy production and environmental remediation

Abstract

Photocatalysis is an efficient technology for energy production and environmental remediation. The composites of metal organic frameworks (MOFs) combined with quantum dots (QDs) allow high photocatalytic ability. Recently, these composites have been applied increasingly in the fields of energy production and environmental remediation. Even so, QD-MOF composites still have some shortcomings in the field of photocatalysis. In this review, the synthesis methods and structures as well as the applications of QD-MOF composites in water splitting for hydrogen production, carbon dioxide (CO2) reduction to produce methane (CH4), organic dye degradation, Cr(VI) reduction, and nitric oxide (NO) oxidation are discussed. The mechanisms of these processes are also described in detail. Finally, new insights into the future development and challenges of the composite are proposed to advance further development of the research area.
