Ion-Exchange Mechanisms in Layered Perovskite Materials
Summary
Layered perovskite materials comprise stacks of corner-sharing octahedral sheets separated by exchangeable interlayer galleries. Ion-exchange mechanisms exploit the intracrystalline reactivity of these galleries to replace native cations or protons with a wide variety of inorganic or organic species. Soft-chemistry routes such as acid leaching, protonation and topochemical intercalation afford precise control over interlayer spacing, surface chemistry and electronic structure. The exchanged species can range from simple alkali or alkaline-earth cations to bulky organic cations, amines or alkoxy groups. Such modifications tune optical absorption, charge-carrier separation and surface reactivity, with direct consequences for photocatalysis, hydrogen evolution, environmental remediation and energy storage. Exfoliation via bulky-cation exchange further yields two-dimensional nanosheets, which enhance specific surface area and ion transport. Overall, the ion-exchange paradigm in layered perovskites underpins the design of hybrid materials with bespoke physicochemical properties and broad practical applications.

Ion-Exchange Mechanisms in Layered Perovskite Materials publication trend
The graph below shows the total number of articles in ion-exchange mechanisms in layered perovskite materials across all publications each year (not limited to Nature Index journals).
Technical terms
Layered perovskite: A structure composed of perovskite-like slabs separated by interlayer galleries capable of hosting exchangeable species.
Ruddlesden–Popper phase: A family of layered oxides with formula An+1BnO3n+1, featuring alternating perovskite slabs and rock-salt layers.
Dion–Jacobson phase: A layered perovskite structure with formula A′An−1BnO3n+1, distinguished by monolayer cations in the interlayer.
Intercalation: The reversible insertion of ions or molecules into the interlayer space of a host material without collapsing its framework.
Protonation: Replacement of interlayer cations by H+ ions, often the first step in ion-exchange processes.
Exfoliation: Separation of layered materials into individual or few-layer nanosheets via chemical or mechanical means to enhance surface area and reactivity.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
