TEM characterisation of novel supported silver and gold nanoparticle catalysts
نویسندگان
چکیده
This project is an extension of TEM work conducted on a previous AINSE funded project AINGRA08066, and aims to use the TEM, STEM/HAADF, EDS and plasmon imaging facilities at ANSTO to structurally characterize novel supported silver nanoparticle catalysts for ozone abatement, and supported gold catalysts for low temperature CO oxidation. The catalysts, fabricated at the University of Auckland, comprise Ag or Au nanoparticles of diameter 1-5 nm deposited on 3-dimensionally ordered macroporous (3DOM) inverse opal silica, titania, alumina and zirconia supports (Ag or Au loadings 1-5 wt. %). From the work, we expect to determine Au particle sizes and size distributions, as well as SiO2, TiO2, Al2O3 and ZrO2 crystallite sizes in the 3DOM supports.

Gold doped TiO2 has been successfully synthesized via the photolysis method and is characterized by different techniques. NPs of gold doped TiO2 were utilized for the degradation of methylene blue as a material pigmentation pollutant. The substitution of Au on TiO2 surface was established via XRD, EDX, TEM, and FT-IR techniques. The TEM and SEM results appea...
متن کاملCO oxidation on TiO2 supported gold catalysts
The aim within this project was to optimise the CO oxidation over TiO2 supported gold catalysts, focusing on two different preparation methods; deposition precipitation (DP) and photodeposition (PD), using different types of TiO2 and varying the theoretical gold loading. The catalyst were characterised with TEM (size) and ICP-AES (loading). For DP catalysts, the support is important for high ac...

متن کاملResonant light scattering spectroscopy of gold, silver and gold-silver alloy nanoparticles and optical detection in microfluidic channels.
Dark field resonant light scattering by gold and silver nanoparticles enables the detection and spectroscopy of such particles with high sensitivity, down to the single-particle level, and can be used to implement miniaturised optical detection schemes for chemical and biological analysis. Here, we present a straightforward optical spectroscopic methodology for the quantitative spectrometric st...
