Features of platinum as the carbon nanocomposites component

Dobrzańska-Danikiewicz A. D., Łukowiec D.

Vol. 66, nr 2

53--61

Purpose: The primary aim of the article is to present the methodology of selection of a noble metal for a constituent component of a Carbon NanoTubes-NanoParticles (CNT-NPs) nanocomposite. The platinum group elements, i.e. Pt, Rh, Rd, Pd, were characterised as part of the works in terms of their suitability for the planned experiments with the weighted scores method. Design/methodology/approach: A dendrological matrix was used for selection of a noble metal, thus employing a procedural benchmarking method. Findings: The heuristic investigations conducted have revealed that, considering the criteria used for the assessment of the potential and attractiveness of the analysed metals, platinum was awarded the highest weighted score for the analysed materials. Practical implications: The CNT-NPs nanocomposites fabricated by deposition of nanoparticles of noble metals onto carbon nanotubes are characterised by subtle electrical properties and a highly developed specific surface, which makes its particularly suitable as active elements of industrial gas sensors such as: H2, CO, CO2, NH3, NO2, CH4, H2S. Moreover, applications are expected of such nanocomposites in biomedicine as glucose and cholesterol sensors. Originality/value: The selection of a platinum group metal as a constituent component of a nanocomposite consisting of carbon nanotubes and nanoparticles, using the procedural benchmarking technique.
