Summary: A series of high-entropy Prussian blue analogues (HEPBAs) were successfully synthesized for the first time in this work, combining mechanochemistry and wet chemistry at room temperature. These materials integrate highly dispersed active sites of high-entropy materials with intrinsic 3D diffusion channels and the redox-active sites of Prussian blue analogues, showing great potential in electrochemical applications.

Summary: Membrane catalysis using two-dimensional materials has shown significant progress in peroxymonosulfate-based processes. In this study, large-scale 2D blade-shaped CoFe Prussian blue analog (PBA) sheets were fabricated using a bottom-up strategy. These sheets were then assembled into a free-standing 2D membrane, which exhibited excellent wetting properties and superior catalytic performance for norfloxacin degradation. The main active species were identified as SO4• and 1O2, which contributed synergistically to the PMS-driven organic degradation.

Summary: Different sizes of alpha-Fe2O3 hollow cubic structures were prepared by calcination of Prussian blue templates, with the transformation mechanism investigated. The gas-sensing performance of pure phase alpha-Fe2O3 hollow cubes to H2S gas demonstrated high sensitivity. Through characterizations, it was found that the optimized sensitivity of 800 nm alpha-Fe2O3 cube was influenced by specific surface area and oxygen vacancy density.
