Two-in-one ultraviolet persistent luminescent catalyst suitable for high concentration photodegradation

Room-Temperature Persistent Luminescence in Metal Halide Perovskite Nanocrystals for Solar-Driven CO 2 Bioreduction

“…The presence of long-lived charges, efficient charge separation, and broad visible absorption strongly indicate the potential application of MHP nanocrystals in photocatalysis and solar-to-chemical synthesis. 38,[40][41][42][43] A lightdriven biosynthetic system with a simple electron conduit was further constructed for the production of fine chemicals from CO 2 based on CsPbBr 3 nanocrystals and enzymes (Figure 3a). This biosynthetic system integrates the highly efficient light-harvesting ability and long-lived charges of CsPbBr 3 nanocrystals with the highly specific CO 2 -processing capability of enzymes.…”

Persistent Luminescent Nanoparticle-Coated Metal–Organic Frameworks for Round-the-Clock Photocatalytic Degradation of Pollutants

“…Therefore, developing a round-the-clock photocatalyst that can continue to operate at night or under dark conditions is essential for environmental protection and energy conservation. Persistent luminescent nanoparticles (PLNPs) absorb ultraviolet and visible light from sunlight and gradually release energy after ceasing external excitation. , The photocatalytic properties of semiconductor-based PLNPs are well known, and certain examples of such materials, such as Zn 2 SiO 4 :Ga 3+ and ZnGa 2 O 4 :Cr, Bi are used for photocatalysis in water treatment. , However, the photocatalytic efficiency of the abovementioned single PLNPs is not sufficiently high owing to their fast e – /h + pair recombination and low specific surface area …”

Enhanced photocatalytic activity of a flower-like In2O3/ZnGa2O4:Cr heterojunction composite with long persisting luminescence

“…28 Many researchers have sought to attain high-efficiency LLP-assisted photocatalyst is using materials such as CaAl 2 O 4 :(Eu,Nd)/TiO 2− x N y , 29 SrAl 2 O 4 :Eu 2+ ,Dy 3+ /g-C 3 N 4 @NH 2 -UiO-66, 30 TiO 2 /Sr 4 Al 14 O 25 :Eu 2+ ,Dy 3+ , 31 Ca 12 Al 14 O 33 :Tb 3+ (Sm 3+ ), 32 (ZnO:Ga 2 O 3 :2GeO 2 ):Cr 3+ /TiO 2 and Zn 2 SiO 4 :Ga 3+ . 33,34 However the photocatalytic properties of these materials still need to be improved. We expect that the combination of In 2 O 3 and ZnGa 2 O 4 :Cr 3+ will prolong carrier lifetimes and improve the band gap of the In 2 O 3 /ZnGa 2 O 4 :Cr heterojunction composite and also will realize a round-the-clock photocatalytic reaction with long persistent luminescence.…”
