Catalysts play a crucial role in many chemical reactions. They can speed up a reaction, reduce the amount of energy needed for a reaction to occur, and even make certain reactions possible. Teaching students about catalysts is important because it not only helps them understand chemistry more deeply, but it also shows them how catalysts are used in the world around them. In this article, we will explore some examples of catalysts that can be used to teach students about this fascinating field of chemistry.
Enzymes
Enzymes are one of the most well-known examples of catalysts. They are biological molecules that help numerous chemical reactions occur in the body. Enzymes act as catalysts by lowering the activation energy needed for a reaction to occur. They do this by binding to specific molecules and changing their shape, making it easier for chemical bonds to be broken and formed. Teaching students about enzymes as catalysts will help them understand how important they are for human health and the role they play in many biological processes.
Platinum Catalysts
Platinum is a powerful catalyst that can be used in numerous industrial processes. It is used in the production of fertilizers, plastics, and even in the refining of crude oil. One of the most famous examples of platinum catalysts is in catalytic converters, which are used in cars to reduce the amount of harmful emissions released into the environment. Platinum catalysts work by changing the chemical structure of the substances they come into contact with, making them less harmful to the environment. Teaching students about the importance of platinum catalysts is crucial for helping them understand the impact of these technologies on the world around them.
Industrial Processes
Catalysts are used in numerous industrial processes, such as the production of ammonia, ethanol, and other chemicals. These catalysts can make the process more efficient, reduce energy consumption, and make the final product purer. Using examples of industrial processes that use catalysts can help students understand how important these chemicals are in today’s world. It can also help to bridge the gap between theoretical chemistry concepts learned in the classroom and real-life applications.
Teaching students about examples of catalysts is important for their development as chemists and scientists. It can help them understand how important these chemicals are in the world around them and inspire them to create new and innovative catalysts that can solve some of the world’s most pressing problems. Teachers should use examples like enzymes, platinum catalysts, and industrial processes to help students understand the importance of catalysts and their role in the world today.
