All-inorganic Pb-free bismuth (Bi) halogen perovskite quantum dots (PQDs) with distinct structural and photoelectric properties provide plenty of room for selective photoreduction CO2. However, the efficient conversion CO2-to-CO high selectivity on Bi-based PQDs driven by solar light remains unachieved, precise reaction path/mechanism promoted surface halogen-associated active sites is still poorly understood. Herein, we screen a series nontoxic stable Cs3Bi2X9 (X = Cl, Br, I) photocatalytic...
Lead (Pb) halide perovskite quantum dots (PQDs) are promising candidates for the photochemical reduction of CO2. However, intrinsically weak adsorption and activation toward inert CO2 molecules have seriously hindered their practical application. This study reports alternative Cs2CuBr4 PQDs gas–solid phase photocatalytic under simulated solar irradiation. exhibited photoreduction performance with CH4 CO yields 74.81 148.98 μmol g–1, respectively. In situ diffuse reflectance infrared Fourier...
CO2 photoreduction currently faces two challenges: low efficiency and poor product selectivity. Ultrathin two-dimensional bismuth oxyhalide, with a large number of surface vacancies (active sites), is an ideal material for regulating photoconversion. However, in this catalyst are easily deactivated during the reaction. relies on sufficient active sites; hence, we synthesized ultrathin Bi4O5Cl2 nanoplates via water-assisted self-assembly process photoswitchable Cl solar-driven CO2-to-CO...
Identifying the dynamic structural changes of active sites in a catalytic reaction under realistic working conditions is great challenge. In this work, we demonstrate that situ electron paramagnetic resonance (EPR) technology an important technique for electronic-level recognition evolution over defective BiOCl catalyst during gas–solid photocatalytic reaction. The formation and recovery photoexcited oxygen vacancies (PE-OVs) with or without UV light irradiation are experimentally verified,...

The complex structural evolution of catalysts under realistic reaction conditions causes great difficulty in identifying true active sites and further understanding the correlations between dynamic behavior catalytic property. Herein, we developed a set operando electron paramagnetic resonance (EPR) measurements to investigate sites, particularly atomic surface structures interfacial processes conditions. By constructing reduced TiO2 as catalyst model, supported by EPR multiple situ...
Photo-catalytic CO 2 reduction with perovskite quantum dots (QDs) shows potential for solar energy storage, but it encounters challenges due to the intricate multi-electron photoreduction processes and thermodynamic kinetic obstacles associated them. This study aimed improve photo-catalytic performance by addressing surface barriers utilizing multiple-exciton generation in QDs. A facile engineering method was employed, involving grafting of ferrocene carboxylic acid (FCA) onto CsPbBr 3 (CPB)...

Preschool teachers can easily become exhausted and worn out, otherwise known as job burnout. Studies have explored the effects of emotional labor strategies psychological capital on burnout; however, few examined their trilateral relationship, especially role with respect to burnout.This study mediating moderating in relationship between three kinds burnout preschool teachers.A cross-sectional was conducted among China. A total 355 completed a self-report questionnaire, including scales that...
Background: Corona virus disease 2019 (COVID-19) is a respiratory infectious and spread rapidly all over the world. Many studies had concluded clinical features of COVID-19, however, comparation between older young patients still unclear. Moreover, mortality correlated with severity disease, indicators for grading inexactly. We aimed to analyzed characteristics COVID-19 compared difference patients. Methods: Patients diagnosed were enrolled. Clinical, radiological laboratory data analyzed....
Abstract All‐inorganic perovskite quantum dots (PQDs) are widely applied in photoelectronics because of their high luminous efficiency. However, PQDs have poor stability, which hinders practical applications. In this study, controllable crystallization is achieved by adding Al 2 O 3 to alter the glass network. Next, Na CO (aq) washing‐heating treatment used improve protective mechanism. Owing dual strategy, prepared CsPbBr @glass exhibits a photoluminescence yield (PLQY > 95%) and...
