Ternary Nanocomposites of Porphyrin, Angular Au Nanoparticles and Reduced Graphene Oxide: Photocatalytic Synthesis and Enhanced Photocurrent Generation

A noble strategy: A photocatalytic strategy toward organic–inorganic ternary nanocomposites of Sn-porphyrin (SnP), angular Au nanoparticles (AuNPs), and reduced graphene oxide (RGO) using SnP as an effective photocatalyst for the reduction of both GO and AuIII under visible-light irradiation. The synergistic effect of surface plasmon resonance excitation in AuNPs and SnP leads to a 27-fold increase in the photocurrent.
