Materials World Modules

An Inquiry & Design-Based Science, Technology, Engineering, and Mathematics (STEM) Education Program

Mini Environmental Catalysis Module

Activities
Using a Heterogeneous Acid Catalysis
Using Photocatalysis to Degrade a Water Pollutant

Design Project
Designing a Catalytic System to Degrade a Pollutant

Through the following key select activities, students learn what a catalyst is, gain an idea of the scope of catalysis research today and become aware of the effect of catalysis on environmental protection. Advances in nanotechnology are also discussed as a solution to eliminate environmental pollutants. Students are challenged to design an original solution to an environmental problem of their choice.

MWM will give students an opportunity to understand the world around them in a way they have never experienced before. The modules promote an awareness of the roles science and technology play in society and guide students to take increased control of their work.

Activity 3: Using a Heterogeneous Acid Catalysis
Students use, recover, and reuse acid catalyst beads to catalyze the hydrolysis of methyl acetate to acetic acid and methanol. They monitor the reaction by testing the pH of the reaction mixture over time. Based on their observations, students infer that heterogeneous acid catalysts are safer and easier to reuse than homogeneous acid catalysts.

Activity 5: Using Photocatalysis to Degrade a Water Pollutant
Students explore the concept of an energy efficient catalysis—room temperature photocatalysis using UV light and titanium dioxide. Monitoring the reaction using color standards, they vary the catalyst concentration, UV light intensity, and pH to test each variable’s effect on the photocatalytic degradation rate of methylene blue dye, which simulates the water pollutant.

Design Project 1: Designing a Catalytic System to Degrade a Pollutant
Using what they learned about catalysis from the Activities, students design and test a functional catalytic system. To be considered successful, the prototype system must meet specific design and performance criteria.
