So far, various methods for evaluating the pore structure of porous materials have been used based on the differences in pore structures. In the micro-pore region, methods such as the HK method, SF method, and CY method based on adsorption potential theory have been employed, while in the meso-macro pore region, classical pore distribution analysis methods such as the INNES method and BJH method based on capillary condensation theory have been used. On the other hand, in recent years, there has been growing attention on new pore distribution analysis methods such as NLDFT and GCMC, which allow for analysis based on a unified theory from micro-pores to meso-macro pores through computer simulations. This document examines which theory, NLDFT or GCMC, is more suitable for pore distribution analysis. Additionally, while the adsorbate proposed by IUPAC 2015 is Ar adsorption, it also investigates the usefulness of N2 adsorption.

Gold-supported catalysts are used in important industrial reactions such as selective oxidation, selective hydrogenation, and water-gas shift reactions, and are known to be very useful catalysts, albeit in a limited capacity. However, even when conducting metal dispersion measurements using the pulse method, which is crucial for evaluating metal-supported catalysts, CO and H2 do not adsorb at room temperature, making accurate evaluation impossible. This document discusses the specific methods and precautions for evaluating the metal dispersion of gold-supported catalysts through CO pulse measurements at low temperatures around -100°C.

Characterization of solid acid catalysts represented by zeolites is frequently conducted using the measurement of acidity through temperature-programmed desorption of ammonia. In this method, it is often observed that the spectrum exhibits two peaks, l (low temperature) and h (high temperature). The l-peak is attributed to ammonia that is further hydrogen-bonded to the NH4+ cation at the acid site and is not considered to indicate acidity. This document provides a detailed description of the specific methods and precautions for steam treatment, which is said to be effective in removing the l-peak. We encourage you to read it.

The measurement of metal dispersion using CO or H2 pulse adsorption methods is a widely applicable technique for measuring the metal dispersion of various metal-supported catalysts. However, there are many metal-supported catalysts where the probe molecules CO and H2 do not adsorb, making the measurement of metal dispersion in those cases difficult. The N2O pulse method is a measurement technique that utilizes the oxidation reaction of surface metals rather than adsorption, and it can be used for catalysts that support metals that are relatively easy to oxidize (such as Cu).

The evaluation of the dispersion of metal-supported catalysts is generally conducted through CO or H2 pulse adsorption measurements. H2 has a weaker adsorption strength to precious metals compared to CO, and depending on the support, it may cause spillover phenomena, which is why it is not often chosen. However, due to its low toxicity and constant stoichiometric ratio, there are cases where H2 is used for pulse adsorption measurements. When H2 pulse measurements are conducted under the same conditions as CO pulse measurements, significantly lower dispersion may be obtained compared to CO pulse measurements. This document examines the causes of this phenomenon and its countermeasures, and reports on the standard measurement conditions for H2 pulse measurements.

The dispersion evaluation of these carbon-supported precious metal catalysts can generally be performed using CO pulse methods; however, in some cases, it may be chosen not to perform oxygen pretreatment to avoid the combustion of the carbon support, leading to variations in measurement conditions among researchers.

Metal-supported catalysts play an important role in industrial processes such as hydrogenation, dehydrogenation, and isomerization reactions. In these metal-supported catalysts, an increase in the dispersion of the metal not only increases the number of active sites effective for the reaction but also enhances the contribution of atoms at the corners and edges of the metal particles, leading to changes in reaction activity and selectivity due to the interactions between the metal and the reactants. Therefore, understanding the metal dispersion is very important in the case of metal catalysts.
