Evaluation of MOF-74, MOF-177, and ZIF-8 for the Removal of Toxic Industrial Chemicals

摘要

Current technology-based efforts are focusing on a nanotechnology approach to sorbent development for air purification applications. Metal- organic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs) are two novel classes of materials that allow for specific functionalities to be designed directly into a porous framework. This report is the second in a series of summary reports based on the evaluation of samples from the University of California, Los Angeles. The samples evaluated in this report are a continuation of a baseline series of materials aimed at collecting design rules for future materials; results from this and the previous report will be used to create a second-generation of reactive MOFs and ZIFs for air purification applications. Testing of the novel materials included nitrogen isotherm data, water, and chloroethane adsorption equilibria, and ammonia, cyanogen chloride and sulfur dioxide breakthrough data.
