Chemical Vapor Deposition: Mn3O4 Nanomaterials Functionalized with Fe2O3 and ZnO: Fabrication, Characterization, and Ammonia Sensing Properties (Adv. Mater. Interfaces 24/2019)

Abstract

Nanomaterials based on Mn3O4 and functionalized with Fe2O3 or ZnO, obtained by a two-step vapor phase process, yield attractive gas sensing responses to ammonia at moderate temperatures. These features are accompanied by detection limits appreciably lower than safety thresholds and good selectivity to NH3 against potential interferents, opening the door to the selective control of ammonia level in a variety of practical contexts by devices with low power consumption.
