Abstract: A bismuth oxide material with a hierarchical structure in gas detection used for detecting the content of low-concentration ammonia in an environment. The bismuth oxide material with the hierarchical structure integrally presents a microsphere shape. The diameter of the microsphere is 1-3 ?m.

The method is simple, easy to operate, high in efficiency and wide in application prospect.
