Abstract 1D zigzag edge‐sharing perovskites have generated intense research interest due to their unique structures and optoelectronic properties. Recent efforts focused on refining these enhance efficiency across various applications. Herein, high‐pressure is utilized modulate the properties of two Pb‐based perovskites, (AMP)PbCl 4 (AMP)PbBr (where AMP 2+ = C 6 H 10 N 2 ), characterized by [PbX ] 2− ∞ chains linked through hydrogen bonding. An inverse excitation‐dependent emission phenomenon enhancement are observed in attributed contraction inhomogeneously coordinated 4− octahedra. Pressure‐induced lattice promotes overlap Pb X orbitals, resulting a decrease bandgap. Concurrently, pressure‐induced phase transitions, distortion octahedra, lead discontinuous decreases These optical structural explorations facilitate systematic design halide with desired characteristics.

Abstract Even distribution of core–shell heterojunction on porous catalyst supports is promising to get the super‐catalysts, yet laborious preparation hinders wide application. A novel strategy urea enzymolysis‐induced ions replacement proposed for one‐pot loading Bi 12 O 17 Cl 2 @Bi 48 Al 75 onto 3 nanorod (named as ‐Bi ). The clever combination enzymolysis and precipitation reactions that consume generated in can switch “on‐off” urease, thus allow precise controlling concentration existence time ions, well replacement. It replacing generate unique structure , it distinctive selectivity 96% benzaldehyde with 90% benzyl alcohol (BA) conversion photocatalytic oxidation BA. replacement, growth mechanism are investigated detail. This work highlights a convenient support, unveils fresh biosynthesis nanomaterials elaborate structure, paves way application nanomaterials.
