NIST Adsorption Workshop Report Now Available

The final version of the summary report from the Measurement Needs in the Adsorption Sciences workshop, held at NIST last November, is now available and, for those of you interested in such measurement issues, it makes for very interesting reading.

Plenary Presentations

The report summarizes the following plenary presentations:

Facility for Adsorbent Characterization and Testing (FACT)

Laura Espinal, NIST

The NIST/ARPA-E Database of Novel and Emerging Adsorbent Materials

Daniel Siderius, NIST

Quenched Solid Density Functional Theory of Adsorption for Heterogeneous Solids and Pore Structure Characterization

Alex Neimark, Rutgers University

Understanding Adsorption/Desorption Hysteresis for Fluids in Mesoporous Materials using Simple Molecular Models and Classical Density Functional Theory

Peter Monson, University of Massachusetts-Amherst

New IUPAC Recommendations: Physisorption of Gases, with Special Reference to the Evaluation of Surface Area and Pore Size Distribution

Matthias Thommes, Quantachrome

The Interplay between Experiment and Simulation for the Design of New Metal-Organic Frameworks

Randall Snurr, Northwestern University

Understanding the Stability of Metal-Organic Frameworks under Humid Conditions

Krista Walton, Georgia Institute of Technology

Characterization of Gas Shales for Enhanced Natural Gas Recovery and Carbon Storage Applications

Jennifer Wilcox, Stanford University

Two-Dimensional Zeolites for Separation Applications

Michael Tsapatsis, University of Minnesota

Frequency Response: A Powerful Technique for Discerning Gas Phase Diffusional Mechanisms and Rates in Nanoporous Adsorbents

Jim Ritter, University of South Carolina

Role of Thermodynamics in Adsorptive Gas Storage Applications

Orhan Talu, Cleveland State University

Breakout Sessions

Then, over the course of the next three chapters, the report covers the discussions that took place in breakout sessions, which focused on three topics:

  • Characterization
  • Advanced Materials for Adsorption Applications
  • Data Harmonization and Standards

And responded to the following focus questions:

  • State of Art
  • Challenges and Barriers
  • Potential Pathways, Solutions, and Approaches

The breakout sessions resulted in lists of topics and issues that need to be addressed, in many areas of adsorption science, sorted into different priority tiers.

The top tiers, in no particular order, included the following points:

Research Needs for Characterization of Adsorptive Materials

Identify complementary independent/multi-technique measurement techniques

Develop techniques for measuring kinetics and diffusion

Develop protocols and devices for rapid assessment of adsorbent performance (less time and high throughput)

Develop in situ and in operando adsorption measurement techniques to characterize “working” adsorbents

Research Needs for Advanced Materials for Adsorption Applications

Establish a standard naming scheme for MOFs

Develop protocols and devices for mixture adsorption measurements and selectivity

Reconcile experimental and simulation results for polar molecules and mixtures, especially water

Improve understanding of chemoselectivity (how does surface chemistry influence competitive adsorption?)

Transition from pellets, beads, and powders to defined structured adsorbents

Research Needs for Data Harmonization and Standards

Encourage consistent, clear reporting of what is being measured/calculated (absolute vs. excess adsorption)

Report data in a conventional manner

Harmonize models and software within commercial apparatus

Provide certified reference materials and data for validation for several material classes

Set uniform activation/pre-treatment conditions

Further details can, of course, be found in the full report, which will be posted online on the Council for Chemical Research website.
