The one-step method for preparing NMAs usually requires a longer cycle to settle the gel (up to several days at room temperature).
“it usually requires a longer cycle to settle the gel (up to several days at room temperature).”
From Ultrafast Generation of Nanostructured Noble Metal Aerogels by a Microwave Method for Electrocatalytic Hydrogen Evolution and Ethanol Oxidation (2021) · cites this paper as [24]
The Results and discussion section says the paper’s one-pot method settles a gel in about 4 hours and is faster than most previously reported noble-metal aerogel methods. It also reports that PdPb hydrogels did not form at room temperature within 12 hours. These passages support a longer gelation time for earlier methods, but not the claimed duration of up to several days at room temperature. (LLM, conf=0.82)
Experimental — accuracy not yet measuredThe network structure and core-shell architecture of metal aerogels increased the exposure of Pt sites.
“MAs increased the exposure of Pt sites [20].”
From Controllable synthesis of Pt-rich shell/Mx core [M = Ni, Fe, Co] metal aerogels as efficient electrocatalysts for hydrogen evolution reaction (2025) · cites this paper as [20]
The Introduction (page unavailable) says noble-metal aerogels can increase the number of active sites, supporting the general idea. The Results and discussion (page unavailable) describe a porous PdPb@Pd aerogel with a Pd shell, but do not show increased exposure of Pt sites. (LLM, conf=0.85)

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.
