Zinc oxide aerogel-like materials with an intriguing interwoven hollow-sphere morphology for selective ethanol sensing

Zinc oxide aerogel-like materials with interconnected multimodal porosity and an intriguing interwoven hollow-sphere morphology were generated from zinc oxide/bacterial cellulose nanocomposite foams by controlled calcination. The monolithic zinc oxide aerogel-like materials with hierarchical porosity and high specific surface area exhibit excellent selective ethanol sensing properties.
