2023年8月15日 · NiTi-LDH/BiOBr exhibits a 100% NO removal efficiency under visible light. Many current studies are focused on the development of 2D/2D nanosystems based on non-traditional semiconductors as efficient visible light-active photocatalysts, due to their interesting structural and optical properties.

2022年5月18日 · Two-dimensional (2D) layered double hydroxides (LDH) are classic materials in fundamental research and practical application. 2D LDH have unique structural features, such as high aspect ratio, high specific surface area, quantum confinement in one direction, layered structure, tunable intercalated anions/interlayer spacing/metal-cation ...

2024年5月1日 · In this study, the synthesis of ALDH was adjusted by sodium dodecyl sulfate (SDS) intercalation and 3-aminopropyltrimethoxysilane (APTMS) surface functionalization. Owing to this modification, the ALDH was delaminated in Pebax solutions, leading to a green process for fabricating 2D ALDH nanosheets incorporated in mixed matrix membranes.

2024年5月15日 · Herein, a novel 2D-on-2D Al-doped NiCo layered double hydroxide (NiCoAl x LDH) nanosheet arrays with high-mass-loading are grown on a carbon cloth (CC) substrate via a two-step hydro/solvothermal deposition strategy, and the effect of Al doping is employed to modify the deposition behavior, hierarchical morphology, phase stability, and multi ...
