Carbon-based semiconductors like carbon nanotubes and reduced graphene oxides (RGO) are suitable candidates for photocatalytic degradation. Incorporation of metal nanoparticle, such as Au, Pd, and Pt are capable of absorbing visible light. Graphene is a two-dimensional hexagonal lattice of carbon atoms and is extremely popular among researchers because of its unusual optical, mechanical, electrical, and catalytic properties. In this work, RGO-Au, RGO-Pd and RGO-Pt photocatalyts are prepared and their excited state dynamics is measured by femotosecond transient absorption spectroscopy. The photocatalytic performance of prepared photocatalyts is investigated by the degradation of Methylene Blue (MB) under UV and visible light.
