Selective Dissolution of A‐Site Cations in ABO3 Perovskites: A New Path to High‐Performance Catalysts
Abstract
Selective dissolution is a common corrosion process in dealloying in which an alloy is immersed in acid to remove the active element, leaving behind an inert constituent. We introduce this technique into the treatment of oxide catalysts. A three‐dimensionally ordered macroporous LaMnO 3 perovskite has been prepared and treated with diluted HNO 3 to selectively remove La cations, acquiring a novel γ‐MnO 2‐like material. LaMnO 3 is not a satisfactory catalyst on CO oxidation. Upon the removal of La cations, the obtained sample showed a significantly higher CO oxidation catalytic activity (T50=89 °C) than the initial precursor LaMnO 3 (T50=237 °C) and ordinary γ‐MnO 2 (T50=148 °C). A large surface area, a high degree of mesoporosity, excellent low‐temperature reducibility, and especially improved surface oxygen species are deduced to be responsible for CO oxidation at lower temperatures.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
