Abstract
IR absorption spectra of films of amorphous carbon (a-C) and a platinum-modified nanocomposite based on amorphous carbon (a-C:Pt) have been studied in the range of stretching vibrations of the carbon skeleton (1200–1700 cm−1) and bending vibrations of C-H bonds (2700–3100 cm−1). It is shown that modification of amorphous carbon with platinum gives rise to an absorption band at 1500 cm−1, which is attributed to platinum-induced destruction of graphene rings of graphite-like fragments into isolated benzene rings. It is concluded that hydrogen “cross-links” benzene rings into graphene clusters, whereas platinum “de-cross-links” graphene clusters.
