Build an Indigo® Zeolite Y molecular model for teaching nanoporous framework for materials chemistry research. Topics can include pore topology, Si/Al tuning, probe molecules, adsorption isotherms, and stability studies.
Zeolite Y (synthetic faujasite) is a foundational model for modern nanoporous materials research. Its well-defined 12-membered ring channels, tunable Si/Al ratio, and high surface area make Zeolite Y a practical demonstration of how framework topology, chemical composition, and pore environment combine to control adsorption, diffusion, catalysis, and stability. Researchers and advanced students use Zeolite Y to study adsorption isotherms, probe-molecule sizing (e.g., N2, Ar, CO2), framework modification strategies, and regeneration/aging behaviors that are broadly applicable to modern MOFs, mesoporous silicas, and other porous solids.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (scroll down to see "Skeletal (Orbit/Minit) and are compatible with every molecular model kit we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
Concept / Probe | Research / Teaching Relevance |
---|---|
N2 (77 K) & Ar physisorption | Standard probes to determine BET surface area, pore volume, and pore-size distribution—ideal for lab demonstrations of characterization. |
CO2 adsorption | Examines high-affinity adsorption sites, framework-guest interactions, and relevance to carbon capture metrics (working capacity, selectivity). |
Probe polyaromatics (benzene, naphthalene) | Used to test pore accessibility, shape selectivity in larger molecules, and to study diffusion/entrapment in micropores. |
Framework modifiers (dealuminated, ion-exchanged variants) | Shows how chemical modification tunes acidity, hydrophobicity, and catalytic behavior—demonstrates materials design principles. |
Category | Representative Molecules / Probes | Relevance / Use in Experiments |
---|---|---|
Inert probe gases | N2, Argon | Surface-area and micropore characterization via adsorption isotherms (BET, t-plot). |
Adsorptive greenhouse probes | CO2, CH4 | Evaluate high-affinity sites and selectivity for environmental applications. |
Polyaromatic probes | Benzene, Naphthalene | Test pore-access thresholds and diffusion/shape-selectivity for larger organic molecules. |
Reactive probes / guest molecules | Water, NH3, small alcohols | Assess hydrophilicity/hydrophobicity, competitive adsorption, and framework stability under humid/chemical stress. |

Really beautiful model! Students have lots of fun and useful discussions while assembling it. Looking at the photographs at the web site was sufficient enough for successful assembly. We are truly satisfied to have this model in our lab.
Visually, this molecular structure of Zeolite Y is beautiful! It received a lot of attention from everyone who passed by it! For the assembly, there is no instruction that comes with the kit and the picture online is the only guide. However, the structure can be made by making 10 sodalite cages and connecting them with bonds via the hexagonal faces (it is helpful to look at the picture while connecting them). Wearing gloves can help provide a better grip while connecting the bonds to the atoms. Overall a good product!
Thanks for the feedback. Trying to describe the assembly was next to impossible so we'll get a picture done of the sodalite cage & add that shortly. Here's a bit more on this model also used for teaching: Zeolite Catalyst Molecular Models Teach Oil Cracking
