Ultrasonic-Assisted Synthesis, Characterization, and Application of a Metal-Organic Framework: A Green General Chemistry Laboratory Project

An instructional research-like multiweek laboratory project for a second-semester introductory general chemistry laboratory course has been developed. The ultrasonic-assisted synthesis method using low cost commercial ultrasonic cleaners has the convenience of running multiple students' reactions simultaneously. Taking advantage of short reaction time, the green metal-organic framework project has been developed to facilitate experimental synthesis, characterization, and application of a porous material and debriefing of results during a normal laboratory period (about 3 h/class). This project provides the opportunity for instructors to introduce students to the Twelve Principles of Green Chemistry, the environmental impact of chemistry, modern solid-state analytical techniques, and a research-like experience of materials science.
