Abstract:

The development of new sensing materials and integrated devices is today one of the most fascinating fields of material science. It stimulates researches for a wide range of applicative areas such as food industry, pollution environment, pharmaceutics and molecular diagnostic and in vitro devices. In this frame, the development of new Ni-based nano-materials for the non-invasive glucose monitoring and gas sensing is receiving great attention due to its high impact in health and environment areas. These materials have been widely investigated as electrodes for electro-catalytic oxidation of analytes by means of the redox couple Ni3+/Ni2+ under alkaline medium. The employment of nanostructures increases both the surface-tovolume ratio and the electron transfer rate boosting the sensing performances. In this work we report a new nanomaterial based on Ni oxide for the detection of NOx. The material exhibited good response towards NOx detection at different temperature. The main advantages of the proposed solution are the easy preparation, high stability and high conductivity which permitted to carried out sensing measurements also at RT.
