摘要

The structural alteration of carbon nanoparticles compared with carbon thin film by heating at 80 ℃ in air was demonstrated. Marked differences in the structural alteration of carbon nanoparticles compared with carbon thin film were elucidated by heating at 80 ℃ in air. It becomes evident that the carbon particles used as the substrate of fuel cell catalysts changed their structure within 1000 h. Graphitization due to heating was demonstrated using a fast Fourier transform (FFT) of the high-resolution image.
