Title  The research of nano metal-oxides on the catalytic

decomposition of the nitrates                     

Abstract

Nowadays, nanostructured materials with specific morphology are great importance in the field of catalysis. This article describes a method for preparing mixture of ammonium nitrate with nano metal oxide, and the different effect of different metal oxides on the thermal decomposition of ammonium nitrate were analyzed. The nanoscale metal oxide TiO2,α-Fe2O3,CuO,ZnO and different size (28 mesh, 60 mesh, 80 mesh) of ammonium nitrate were mixed. Nano metal oxide and the mixture form was observed using scanning electron microscope. Thermal decomposition characteristics of the mixture of ammonium nitrate and nano metal oxides were tested using TG and DSC. The catalytic decomposition properties on ammonium nitrate with different nano metal oxide were compared, and the effect of ammonium nitrate with different particles size on thermal decomposition were analyzed also.

Keywords: Nano metal oxide; ammonium nitrate; Catalytic decomposition
