General Synthesis of Periodic Macroporous Solids by Templated Salt Precipitation and Chemical Conversion
Abstract
This paper presents a general method to prepare three-dimensionally ordered macroporous (3DOM) metal oxides or carbonates via templating with polystyrene (PS) spheres. The method is based on templated precipitation of metal salts (acetates, oxalates, oxides) within a colloidal crystal of PS spheres and subsequent chemical conversion of the inorganic precursors. The compositional range of possible macroporous products includes oxides or carbonates of many metals in the periodic table (e.g., MgO, Cr 2 O 3, Mn 2 O 3, Fe 2 O 3, Co 3 O 4, NiO, ZnO, CaCO 3 ), including compositions that are less accessible or more expensive by previous syntheses based on metal alkoxide precursors. Optimal synthesis conditions and structural features of selected materials are described, on the basis of XRD, TGA, SEM, TEM, nitrogen adsorption data, and chemical analysis.

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.
