A targeted corrosion inhibitor for marine reinforced concrete, and a preparation and application thereof. The targeted corrosion inhibitor is a nano silver-loaded nitrite-intercalated layered double hydroxide. The targeted corrosion inhibitor is prepared based on interlayer ion exchangeability of layered double hydroxides and specific recognition of Ag.sup.+ to chloride ions.

Methods of making permeable aerogels (100) can include providing a sol mixture (110) comprising an organic scaffold, an inorganic aerogel precursor, and a first solvent. The organic scaffold can be insoluble in the first solvent. The sol mixture can react to form a gel (120) such that an interconnected channel network is formed which is at least partially defined by the organic scaffold. The first solvent in the gel can be exchanged (130) with a second solvent. The second solvent can dissolve the organic scaffold to expose the interconnected channel network. The gel can be dried (140) to form the permeable aerogel.
