| Outline of Final Research Achievements |
In this study, commercially available versatile alloy substrates, such as Ni-Cu and Cu-Mn alloys and stainless steels, were heat-treated at relatively low temperatures and their self-formed surface oxide layers were examined as electrocatalysts for glucose oxidation and as growth catalysts for nanocarbon materials. In the case of electrocatalytic application, a Ni-Cu alloy substrate that was preheated at optimized conditions exhibited superior electrochemical glucose oxidation ability under alkaline conditions. To examine the application of nanocatalyst layers as synthetic catalysts for nanocarbon growth, a variety of nanocarbons were synthesized on the surfaces of preheated stainless steels and Ni-Cu alloys by employing the liquid-phase synthesis process. Furthermore, detailed surface characterization of each preheated substrate was also conducted for identifying the associated catalyst species and for analyzing the mechanism of each catalytic reaction.
