Done By: Gold Group School Name: Mohamed Bin AbdelAziz Al-Mana Independent School Environmental Catalysis Module: Students examines different types of catalytic systems, including heterogeneous and homogeneous catalysis. Depending on the knowledge they gained during activities, the students are then asked to design their projects. Our Project: Using Ni-Ga catalyst to reduces CO2

- 6. reactions go fasterand with less energy. Because catalysts are not consumed, they are recycled. Often.only tiny amountsare required Activity 2:CATALYSIS
- 7. The first time a catalyst was used in the industry was in 1746 by J. Roebuckin the manufacture of lead chamber sulfuric acid. Since then catalysts have been in use in a large portion of the chemical industry Industrial catalysts
- 8. Enzymes are thecommonest and most efficientof the catalysts foundin nature.Most of thechemical reactions thatoccur in thehumanbody and in other living things are high-energyreactions thatwould occur slowly, if at all, withoutthe catalysis provided by enzymes. For example, in theabsence of catalysis, it takesseveral weeks for starch to hydrolyze to glucose. catalyst in nature
