20.500.12556/DiRROS-22559 Efficient decoration of graphene oxide with a narrow size distribution of noble metal nanoparticles green reduction and integration into a thermoelastic composite Efficient decoration of graphene oxide with a narrow size distribution of noble metal nanoparticles: green reduction and integration into a thermoelastic composite We have developed a significantly enhanced method for the effective and homogeneous decoration of graphene oxide (GO) and reduced graphene oxide (r-GO) flakes with gold (Au) and platinum (Pt) nanoparticles. This method involves the direct nucleation of nanoparticles on the surface of dispersed GO through a single-step reaction. By carefully controlling the stepwise introduction of gold and platinum complexes at elevated temperatures, without additional reducing agents, we successfully achieved a homogeneous distribution of Au and Pt nanoparticles, ∼ 20 nm and ∼ 3 nm in size, densely covering the GO sheets. The decoration yield in a mass ratio between Au and GO was up to 20 %. Reduced GO with attached gold and platinum nanoparticles was obtained using ascorbic acid as a reducing agent. Finally, we embedded Au-decorated r-GO in polydimethylsiloxane (PDMS) to form a composite. We show how this stable hybrid material composite can be spin-coated to form a thin thermoelastic film on a flexible substrate, enabling promising photoacoustic properties that could be exploited further in biomedical applications. graphene oxide decoration nanoparticles nanocomposites grafenov oksid nanodelci nanokompoziti true false true Elsevier Nizozemska Angleški jezik Slovenski jezik © 2025 The Authors.
