Temperature programmed desorption of NH3-TPD ammonia is an experimental method to characterize the acidic site (active site) and acid strength of the catalyst. In this experiment, the catalyst needs to pre-adsorb ammonia gas, and then heat it at a fixed heating rate under carrier gas purging, so that the carrier gas pa......
