Electron spin resonance spectroscopy(ESR)was used to investigate the effects of hydrogen ion concentration and hydroxide concentration in perchloric acid system and sodium hydroxide system on the state and behavior of free radicals generated by hydrazine bond breaking catalyzed by catalysts.The difference of free radicals generated by Pt/SiO2 cata-lyzed hydrazine decomposition in acid-base system was determined.The results show that in the alkaline system,with the increase of hydroxide concentration,the N-H bond breaking rate increases signific...
