Supported nickel oxide catalysts have a wide range of applications in petrochemical industry. This work reports the results of a micro-PIXE measurement of Ni distribution in a supported nickel oxide catalyst over individual silica base particles, 60-200 {mu}m in size. These catalysts were synthesized with 1% and 5% then calcined at 400 {degrees}C. A 2.5 MeV proton microbeam was used to scan the samples of individual grains. Two dimensional distribution maps of Ni and Si have been measured. This paper discusses the important effects of the process of calcination on the distribution of Ni. The effects of different nickel loading and other synthesis conditions will also be discussed.
