N2 - This work reports a comprehensive study on the synthesis and characterization of Au-TiO2 Janus nanostructures from pre-synthesized Au nanoparticles and anatase TiO2 nanoparticles. Here, well-distributed Au nanoparticles with mean particle diameter of ∼35 nm were successfully prepared using seed-mediated method, which exhibited a unique surface plasmon resonance (SPR) properties at 525.5 nm. Meanwhile, anatase TiO2 nanoparticles with perfectly spherical morphology were synthesized via sol-gel method, which could easily be integrated by the as-prepared Au nanoparticles. Based on the result, it is found that the resultant nanostructured exhibited a Janus heterostructure feature, where Au nanoparticles were efficiently found to be attached on the surface TiO2 nanoparticles. Furthermore, spectroscopic analyses also revealed that the integration of Au nanoparticles could widen the absorption spectrum of TiO2 to visible range due to the presence of SPR phenomenon.
