Splet21. avg. 2014 · Each TPD measurement lasted 3 h. The amount of water desorbed from each porous material during the TPD experiments was calculated by using a calibration factor, which was obtained by measuring the area under the TPD profile corresponding to a known amount of desorbed water from a calibration sample.

It is however emphasized that the ubiquitous TPD experiment is governed by the equilibrium between ammonia molecules in the gas phase and on the surface. SpletAs TPD experiments are commonly performed, the temperature is controlled by a computer to increase linearly with time: T = T 0 + b H t. Here, b H is the heating rate or "ramp rate". … jotashield decor glaze
