Functionalized nanomaterials ZnO:PdO for gas sensors

Abstract

The emergence of a hydrogen economy provides the impetus for the production of low-cost, simplemaintenance, easy-to-install, easy-to-use, and accurate hydrogen sensors suitable for use by untrained individuals in a variety of applications. One of the sensors that can detect hydrogen are structures based on nanostructured ZnO films functionalized with Pd nanodots. The use of Pd nanodots made it possible to obtain sensors that can detect high hydrogen concentrations even at low operating temperatures. Thus, in this paper it is proposed to obtain new sensors that can detect hydrogen based on ZnO:PdO nanomaterials.
