Herein, we present the effectiveness of using an atmospheric pressure dielectric barrier discharge (DBD) plasma torch for gold (Au) nanoparticle (NP) decoration of TiO2 nanoparticles and nanotubes (NTs). Au NPs were synthesised using an aerosol of HAuCl4·3H2O solution that was carried with an inert gas to the near plasma post-discharge zone. Careful optimisation of the deposition parameters was done to ensure the uniform and dispersed decoration of TiO2, demonstrated by scanning and transmission electron microscopy with energy dispersive spectroscopy. The X-ray diffraction was used to confirm that the deposit was pure metallic Au. Unlike the bare TiO2 nanoparticles, the samples with Au NPs showed the plasmon resonance peak in the region of 500-600 nm. The photocatalytic property enhancement of Au NP decorated TiO2 structures was demonstrated: The TiO2 NPs@Au nanoparticular powder showed improved photocatalytic activity by enabling methyl orange dye degradation 35% faster than that of t...he pristine TiO2 NPs; superior photocatalytic behaviour of TiO2 NTs@Au thin films compared to bare TiO2 NTs was observed in the photodegradation of stearic acid.
