Solution Combustion Synthesis of Nano Materials

摘要

The results on novel approaches for synthesis of nano-sized materials by utilizing a Solution Combustion (SC) method are presented. Four different reaction modes were investigated, including Volume (VC), Sol-Gel (SGC), Impregnated Paper (IPC) and Impregnated Support (ISC) Combustions. By using these approaches complex La_(0.6)Ce_(0.4)Fe_(0.68)Ni_(0.2)K_(0.12)O_3 perovskite-based catalysts were synthesized. Obtained products were characterized by their microstructures and specific surface areas (SA). The range of the SA for as-synthesized samples was 20-50m~2/g with the following order for the SA values: IPC～VC < SGC < ISC. The catalysts activities were tested for auto thermal reforming of the high hydrocarbon fuel (JP-8 surrogate with 10 ppm of sulfur) for hydrogen production. All synthesized catalyst showed a high fuel conversion and stable performance. It was also revealed that catalysts activity has no direct correlation with their SA but it mostly depends on the powder sinterability.
