Abstract
Texture investigations of a series of InCat Pt reference catalysts prepared on a large scale are presented, including some basic characteristics: specific surface area, pore volume, average pore size. All the samples have clearly demonstrated a mesoporous structure. The preparation procedure did not modify appreciably the surface area or the pore volume, but substantially changed the pore size distribution. Such reference platinum catalysts can be used for test and calibration purposes and for co-ordination of new investigations. In addition, a short summary of the standardisation of the surface area determination by the BET-nitrogen adsorption method is presented. A set of Russian state standard samples for calibration of instruments for specific surface area measurement of various dispersed and porous materials is described.
