Abstract

The term aerogel is used for unique solid-state structures composed of three-dimensional (3D) interconnected networks filled with a huge amount of air. These air-filled pores enhance the physicochemical properties and the structural characteristics in macroscale as well as integrate typical characteristics of aerogels, e.g., low density, high porosity and some specific properties of their constituents. These characteristics equip aerogels for highly sensitive and highly selective sensing and energy materials, e.g., biosensors, gas sensors, pressure and strain sensors, supercapacitors, catalysts and ion batteries, etc. In recent years, considerable research efforts are devoted towards the applications of aerogels and promising results have been achieved and reported. In this thematic issue, ground-breaking and recent advances in the field of biomedical, energy and sensing are presented and discussed in detail. In addition, some other perspectives and recent challenges for the synthesis of high performance and low-cost aerogels and their applications are also summarized.

  • Non-precious alternatives such as metals/alloys, their oxides/phosphides/sulfides/selenides/nitrides/carbides, metal-free carbon, single atoms, and composites hold high promise for use in electrochemical water splitting.

    “These materials have been widely reported and hold high promise for use in electrochemical water splitting.”

    From Silica Aerogels as a Promising Vehicle for Effective Water Splitting for Hydrogen Production (2025) · cites this paper as [25]

    The 'Aerogels for Energy' section discusses aerogels for supercapacitors and batteries, but does not address the listed non-precious alternatives for electrochemical water splitting. Searches for those materials and for water-splitting electrocatalysts found no passage supporting that application in our copy. (LLM, conf=0.74)

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.
