Done By: Unique Group
School Name: Qatar Secondary School for Girls

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: Factory’s smoke contains many harmful and dangerous materials for both human beings and the environment, this project will not only save our ozone layer but it will save many people in the future generation securing a breath full future for humanity.

Qatar environmental catalyst - unique group-2014

  1. 1. Al-Bairaq I am discovering materials Environmental catalysis Group name: Unique Maha Ahmed Hissa Alkuwari Sara Faraj Fatma Alkubaisi
  2. 2. : Decomposition of Hydrogen Peroxide with yeast as a catalyst Internet Hunting. : Using a heterogeneous Acid Catalyst. Using Metal catalyst to Degrade an Air Pollutant. Using photo catalysis to degrade a water pollutant Smoke Filtering System
  3. 3. • A substance when added to a chemical reaction between two reactants, causes an increase in the reaction’s rate while in the same time is not consumed by the reaction at all and returns to its original state after the reaction has ended.
  4. 4. to decompose H2o2 using Yeast as a catalyst.
  5. 5. Bubbles of Oxygen and also colorful water. Yeast H2O2 Soap + food dye
  6. 6. 1. Speed up chemical reactions which is time saving. 2. Decreases the heat required to carry out a chemical reaction which is energy saving. I. Yeast : used to help decompose Hydrogen peroxide into Oxygen and water. II. Vanadium pentoxide (V2O5) : used to help in the contact process to produce sulfuric acid. III. Alumina (Al2O3) : used in the Claus process for converting hydrogen sulfide waste gases into elemental sulfur
  7. 7. Using a Heterogeneous Acid Catalyst : to use a heterogeneous catalyst 1. Methyl acetate solution 2. Methyl acetate solution + a catalyst – beads- 3. Distilled water + a catalyst –beads- 1. Label 3 beakers with the name s of the reactants. 2. Do a table on the PH scale of the solutions and record the PH every 3 minutes. 3. Compare the results
  8. 8. 1 2 3 4 5 6 7 (MA) solution (MA) solution +catalyst distilled water Decomposition of materials 0min 3min 6min 9min 12 15 18 the reaction was active and fast in the 2nd beaker, because : 1. The first beaker only had the solution with no catalyst to make the reaction faster. 2. The catalyst added to the 3rd beaker doesn’t work on water it works on the Methyl acetate.
  9. 9. Using Metal Catalyst to Degrade an Air Pollutant 1. to degrade an Air pollutant (Ammonia) using a Metal Catalyst (Iron Fiber, copper turning and copper granule) 1. Obtain the metal catalyst: iron fibers. 2. Set up apparatus as show. 3. Place catalyst into the reaction tube to make a 2.5 cm length in the center of the glass tube.
  10. 10. Iron fiber became poisoned very quickly unlike the other metal catalysts which are copper turnings and copper granules, are the ones that lasted the longest.
  11. 11. to use Photo catalysis to degrade Methylene Blue (MB).
  12. 12. • Introduction: Factory’s smoke contains many harmful and dangerous materials for both human beings and the environment, this project will not only save our ozone layer but it will save many people in the future generation securing a breath full future for humanity.
  13. 13. manganese dioxide is excellent to use in a filter to convert the amount of carbon monoxide coming out of factories into Carbon Dioxide which is less harmful. 1. It has outstanding abilities in converting CO into CO2 2. Unlike other catalysts used to clear smoke it is very cheap which is a great financial opportunity. 3. It has no known hazards to the environment.
  14. 14. Exposure to CO can reduce the oxygen- carrying capacity of the blood. And that leads to CO poisoning which leads to headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. High levels of CO inhalation can cause loss of consciousness and death, People who are sleeping or intoxicated can die from CO poisoning before ever experiencing symptoms.
  15. 15. What It’s Made of: 1. Box 2. Tube 3. Cotton with MnO2 powder 4. Metal plate 5. Something that burns. How Does it Work 1. Burn something 2. Let the smoke get into the tube which has the catalyst 3. Measure the concentration of CO2 before it went through and after

  17. 17. Since the concentration of carbon dioxide increased then that’s that means that carbon monoxide was converted into carbon dioxide. 0 1000 2000 3000 4000 5000 6000 7000 8000 0sec 30sec 60sec 90sec CO2 Concentration Smoke + Catalyst Smoke
