Mechanochemical Synthesis of Lead‐Free Halide Layered Double Perovskites: A Green and Scalable Approach

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Herein we report a facile, green, and scalable synthetic alternative for the obtention of layered double perovskites (LDPs) via mechanosynthesis. This approach allows for the synthesis of phase‐pure LDPs in batches of up to 5 g within minutes. To our knowledge, this represents the largest scale and fastest synthesis of these materials reported to date.
