Au catalysts supported on different carbon materials, such as graphite (G, 10m2g− 1), ribbon- type carbon nanofibers (CNF-R, 109m2g− 1), and carbon nanospheres (CNS, 3m2g− 1), were prepared by the sol–gold method using tetrahydroxymethyl phosphonium chloride as the reducing agent. Different techniques were employed to characterize both the supports and the final Au catalysts: atomic absorption spectrometry, transmission electron ...
