Preparation of a low‐density , high‐ surface‐area SnO 2 aerogel (see Figure inset), comprised of interconnected, randomly oriented crystalline (rutile) SnO 2 nanoparticles ∼3–5 nm in size is reported. X‐ray absorption near‐edge structure spectroscopy at the Sn M 4,5 edge reveals that the electronic structure of the SnO 2 aerogel is similar to that of tetragonal SnO, rather than SnO 2 or β‐Sn, with additional Sn‐related electronic states close to the conduction band minimum.
