CdS QDs modified three-dimensional ordered hollow spherical ZnTiO3-ZnO-TiO2 composite with improved photocatalytic performance

Designing advanced S‐scheme CdS QDs/La‐Bi2WO6 photocatalysts for efficient degradation of RhB

“…The results showed that a Z-scheme heterojunction was formed between the two substances through modifying CdS QDs and the spatial separation efficiency of photogenerated electron holes was increased by creating synergies between oxygen vacancies and heterojunctions, which showed good photothermal and photocatalytic properties. An et al [45] successfully prepared a 3DOH ZnTiO 3 -ZnO-TiO 2 multicomponent composite material using CdS QDs-assisted modification. The heterostructure formed greatly improved the hydrogen production efficiency (≈300 times vs TiO 2 ).…”

Solid Additive Enables Organic Solar Cells with Efficiency up to 18.6%

“…Therefore, the selection of donors, acceptors, and additives with complementary advantages and compatibility is the key to enhance the photovoltaic performance parameters, such as open-circuit voltage ( V OC ), short-circuit current density ( J SC ), and fill factor (FF) . Meanwhile, a donor with lower highest occupied molecular orbital (HOMO) energy level or an acceptor with higher lowest unoccupied molecular orbital (LUMO) energy level was introduced as an additive to regulate the V OC ’s of OSCs. − In addition, the compatibility and crystallinity of the additives are critical to optimize phase separation and molecular alignment. , Accordingly, for the selection of solid additives, a combination of compatible mixing, complementary light absorption, and matched energy level should be considered to prepare high-performance OSCs.…”

Recent Progress on Carbon Quantum Dots Based Photocatalysis

“…The unique properties of CQDs enable their applications in photocatalysis ( Murali et al, 2021 ; Syed et al, 2021 ; Yao et al, 2022 ), where photogenerated electrons and holes do the job. The UCPL of CQDs makes the use of the full spectrum of solar light possible to increase the light absorption and thus the photogenerated electrons and holes ( Wang and Hu, 2014 ; Farshbaf et al, 2018 ; An et al, 2022 ; Preethi et al, 2022 ; Saeidi et al, 2022 ; Su et al, 2022 ). The efficient photo-excited electron transfer of CQDs retard the recombination of electron-hole pairs to increase the lifetime of photogenerated electrons and holes ( Liang et al, 2021 ; Liu et al, 2021 ; Mahmood et al, 2021 ).…”
