“…The catalytic disproportionation of CO to carbon clusters has also been observed on roughened gold films. 25,26 It is not clear from the current studies exactly how the presence of carbon effects the catalytic activity of the gold nanoparticles, but it does not seem to inhibit the gas generation process.…”

“…Studies by Kudelski [21] on the SERS of a carbon film assigned to amorphous carbon (bur potentially also containing pyrolytic graphite) was studied. Kudelski et al [21] assigned the SERS as arising from surface enhancement for species adsorbed at plasmon 'hot spots' on the metal surface with the spectral fluctuations indicating continuously progressing surface chemistry at discrete locations. The reported temporal Raman features in this study [21] resemble the spectral features reported here.…”

Studies have shown that for o-SWCNT compounds are highly pure, with carbon based impurities been removed.…”

“…Estudos mostraram que moléculas de CO 2 do ar podem ser a fonte de carbono destas contaminações 87 , bem como o próprio adsorbato 5 . Kudelski e Pettinger 88 obtiveram os espectros SERS de carbono amorfo depositado sobre eletrodos de Au e Ag e mostraram que este material em pequenas quantidades pode apresentar sinal intenso devido sua adsorção nos "hot spots". Os substratos metálicos também podem conter óxidos na superfície quando expostos ao ar.…”
