An object of this invention is to provide an air bag azide-free gas generating composition which can pronouncedly reduce the concentrations of toxic components in the after gas, especially both concentrations of CO and NOx while retaining the desired advantages of azide-free gas generating compositions. The air bag gas generating composition of the invention is an azide-free gas generating composition comprising a nitrogen-containing organic compound and an oxidizing agent as active components, and further contains, as a burning catalyst, at least one metallic oxide selected from the group consisting of molybdenum oxides, tungsten oxides and metallic oxides having a BET specific surface area of at least 5 m2/g.
本发明的目的是提供一种气囊无氮气体发生组合物,它可以明显降低尾气中有毒成分的浓度,特别是一氧化碳和氮氧化物的浓度,同时保留了无氮气体发生组合物所需的优点。本发明的气囊气体发生组合物是一种无叠氮气体发生组合物,包括作为活性成分的含氮有机化合物和氧化剂,以及作为燃烧催化剂的至少一种金属氧化物,这些金属氧化物选自钼氧化物、钨氧化物和 BET 比表面积至少为 5 m2/g 的金属氧化物。
