The specific surface area is a number that characterizes the surface area of solids, especially porous solids. Expressed in surface area per unit mass, the SI unit is m2/g....

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......

The determination of the true density of carbon materials is currently the standard method in ferrous metallurgy industry. ...
