Theoretical and practical discussion of measurement accuracy for physisorption with micro- and mesoporous materials
چکیده انگلیسی

The surface area and pore size distribution are two very basic properties of a solid catalyst powder. Physisorption is still the only macroscopic method for measuring these two properties. To better understand the pore structure and surface properties of materials, it is very important to make accurate physisorption measurements. Unfortunately there are still many misunderstandings about physisorption. In fact, hardware design, operation of the instrument and data reduction can all contribute to the accuracy of a measurement. In this paper, the measurement accuracy of physisorption was discussed from these three aspects.

Graphical AbstractTo meet higher and higher accuracy requirements for micro- and mesoporous materials' physisorption analysis, the hardware design, operation, and data reduction process all make contribution.Figure optionsDownload as PowerPoint slide
