NiS nanostructures were synthesized using a microwave-assisted wet chemical hydrothermal technique. XRD analysis of the product obtained after washing the product and drying it at 90 °C for 6 hours confirmed that α-NiS and β-NiS phases were formed. Au nanostructures were deposited on the surface of the NiS product via a microwave-assisted impregnation technique. H2 gas sensitivity of NiS or Au/NiS...
The mobility of surface-bound metallic nanoparticles (NPs) on catalyst supports results in agglomeration leading to a subsequent decrease in effectiveness of the catalytic behavior of the metal NPs over time. We report here the synthesis and characterization of a carbon nanotube (CNT) catalyst support system enhanced with ‘docking stations’ along the exterior which limit the surface mobility of ultra...
