Abstract Preparation of oxygen by hydrogen peroxide in junior high school chemistry textbook did not specify the mass of catalyst, and the powdered catalyst was difficult to recycle and reuse. Through orthogonal experiment method and combined with handheld technology, this paper inquired the optimum conditions for decomposition of hydrogen peroxide catalyzed by manganese dioxide immobilized on cement, and solved the problem of recycling and reuse of the catalyst.
