Summary: In recent years, halide perovskites have shown great potential in X-ray detection due to their excellent optoelectronic properties and high X-ray attenuation coefficient. However, large-scale perovskite production for high-performance X-ray detectors is still very challenging. In this study, a combination of ultrasound-assisted crystallization and hot-pressing method is used to prepare a large-area and high-quality quasi-monocrystalline thick film of a mixed-cation perovskite MA(0.42)FA(0.58)PbI(3). This approach provides a more uniform nucleation and fusion of crystal boundaries, resulting in a quasi-monocrystalline film with improved carrier mobility and sensitivity. This research demonstrates the potential of the ultrasound-assisted crystallization and hot-pressing strategy for industrial applications in X-ray detection.

Summary: This study proposes an atomic activation method to design a flower-like NiAl-LDH/CeO2 hybrid heterojunction for selective CH4 photosynthesis. The electrons in the NiAl-LDH nanosheets spontaneously migrate to CeO2, forming an internal electric field that drives S-scheme charge transfer upon visible-light illumination. Additionally, the decorated CeO2 nanoparticles optimize the electronic structure and activate the originally inert Ni and Al atoms on NiAl-LDH, serving as potential active centrals. As a result, the NiAl-LDH/CeO2 heterojunction exhibits higher CH4 yield rate and selectivity compared to pristine NiAl-LDH and CeO2 materials. This work highlights an atomic activation technique for LDH-based heterogeneous photocatalysts, providing a new vision for developing efficient hybrid material systems for CO2 conversion applications.
