No. 2 Evaluation of BET Surface Area of Porous Silica

No. 2 Evaluation of BET Surface Area of Porous Silica

This is an introduction to the evaluation of the BET specific surface area of porous silica (Type IV adsorption isotherm)!

This document introduces the evaluation of the BET specific surface area of porous silica (Type IV adsorption isotherm) using graphs and other materials. The specific surface area (surface area per unit mass) of a powder with a certain mass increases with the presence of pores or when the particle size becomes smaller. This specific surface area can be evaluated using the BET theory based on three assumptions derived from the adsorption isotherm. In the case of Type II and IV adsorption isotherms, the BET equation is linear in the range of p/p0 = 0.05-0.3 (the relative pressure range where a monolayer is formed). 【Three Assumptions of BET Theory】 ■ Surface energy is uniform ■ There is no interaction between adsorbed molecules ■ The adsorption energy for the second layer and beyond is equal to the condensation energy *For more details, please refer to the PDF document or feel free to contact us.

Evaluation of BET specific surface area of No. 3 activated carbon (Type I adsorption isotherm)

Evaluation of BET specific surface area of No. 3 activated carbon (Type I adsorption isotherm)

[Information] Underestimating the specific surface area! An introduction to the evaluation of the BET specific surface area of activated carbon (Type I adsorption isotherm).

This document introduces the evaluation of the BET specific surface area of activated carbon (Type I adsorption isotherm) using graphs and other materials. Activated carbon and zeolites with micropores typically exhibit Type I adsorption isotherms. When evaluating the BET specific surface area of these materials, the large curvature of the micropores and the constraints on the packing of the adsorbate prevent the formation of multilayer adsorption, thus invalidating the BET theory and leading to an underestimation of the specific surface area. This document explains the evaluation method for the BET specific surface area of such Type I materials. *For more details, please refer to the PDF document or feel free to contact us.*

Evaluation of low specific surface area by Kr adsorption measurement No. 6

This is a document introducing the evaluation of low specific surface area using Kr adsorption measurement!

This document introduces the evaluation of low specific surface area using Kr adsorption measurements. In the evaluation of low specific surface area materials such as non-porous metal materials, glass substrates, and low-k films, the BET specific surface area is evaluated from the Kr@77.4K adsorption isotherm instead of N2@77.4K. Why is this the case? The document also explains the applicable range. Please take a moment to read it. *For more details, please refer to the PDF document or feel free to contact us.

Evaluation of Mesopores in Porous Silica by the BJH Method No. 7

Evaluation of Mesopores in Porous Silica by the BJH Method No. 7

This is a document introducing the evaluation of mesopores in porous silica using the BJH method!

This document introduces the evaluation of mesopores in porous silica using the BJH method, utilizing graphs and other visuals. The pore distribution of mesopores, analyzed using the BJH theory (Barrett-Joyner-Halenda), is based on three assumptions derived from the adsorption isotherm. Due to capillary phenomena, the saturation vapor pressure of the adsorbate decreases within mesopores (macropores) at a given temperature, leading to the condensation of the adsorbate (= capillary condensation). 【Three Assumptions of BJH Theory】 ■ Pore shape is cylindrical ■ The meniscus is hemispherical with a contact angle of 0° ■ Correction for the adsorbed layer (thickness t) *For more details, please refer to the PDF document or feel free to contact us.

Evaluation of Various Materials Using No. 9 T-Plot Method (Basic Edition)

Evaluation of Various Materials Using No. 9 T-Plot Method (Basic Edition)

[Information] This is an introduction to methods that can determine the surface area and pore volume of various materials!

This document introduces various material evaluations using the t-plot method (basic edition) with graphs and tables. The t-plot method, devised by Lippens and de Boer, is a technique that allows for the determination of surface area and pore volume of various materials. By converting the adsorption branches of the N2@77.4K adsorption-desorption isotherms for non-porous quartz sand (a), high-silica zeolite with micropores (b), and porous silica Develosil with mesopores (c) using the reference t-curve of non-porous silica (SiO2), we will examine the respective surface areas and pore volumes. *For more details, please refer to the PDF document or feel free to contact us.

Evaluation of MCM-41 Structure Using No. 11 t-plot Method (Application Edition 2)

Evaluation of MCM-41 Structure Using No. 11 t-plot Method (Application Edition 2)

[Data] Evaluation of MCM-41 Structure of Mesoporous Silica by t-plot Method (Application Edition 2)

This document introduces the structural evaluation of mesoporous silica MCM-41 using the t-plot method (Application Part 2) with graphs and tables. The N2 adsorption-desorption isotherm of mesoporous silica MCM-41 at 77.4K is classified as Type IVb, indicating the presence of mesopores. When examining the t-plot using silica as the reference t curve based on this isotherm, an upward shift due to capillary condensation is observed, confirming the presence of mesopores. *For more details, please refer to the PDF document or feel free to contact us.*

Evaluation of Pore Structure by No. 21 NLDFT Method and GCMC Method

Evaluation of Pore Structure by No. 21 NLDFT Method and GCMC Method

What are the optimal analysis methods and adsorbates for understanding the pore structure of porous materials? Various materials will be introduced as examples.

The NLDFT method assumes pore shape (pore diameter) and determines parameters at the adsorption temperature and pressure, using an approximate formula based on density functional theory for the adsorption density within the pores. The GCMC method calculates the adsorption density through computer simulations that model the adsorption phenomenon after determining the parameters. This document examines which theory, NLDFT or GCMC, is more suitable for pore distribution analysis, and how useful N2 adsorption is. We encourage you to read it. 【Contents (partial)】 ■ Figure 1 Local isotherms for 4nm and 10nm using NLDFT and GCMC (adsorption branch Ar@87.3 K) ■ Figure 2 Adsorption isotherms for MCM41 (N2@77.4 K, Ar@87.3 K) ■ Figure 3 Pore distribution (pore volume) for MCM41 (N2@77.4 K, Ar@87.3 K) ■ Figure 4 Adsorption isotherms for MFI1000H (N2@77.4 K, Ar@87.3 K) ■ Figure 5 Pore distribution (pore volume) for MFI1000H (N2@77.4 K, Ar@87.3 K) *For more details, please refer to the PDF document or feel free to contact us.
