Catalysts in Industry
Catalysts are popular in industry for many reasons. But, there are disadvantages to using catalysts.
Advantage - cost-effective
Advantage - cost-effective
- Despite the fact that some catalysts are expensive precious metals (e.g. platinum and palladium), they are often cost-effective to use.
- This is because a small amount can speed up a reaction by a lot. It may be cheaper to pay for the catalyst at the start and increase the rate of reaction after that.
- Paying for a catalyst may be cheaper than paying for the energy needed to increase either temperature or pressure.
Advantage - reduced burning of fossil fuels
Advantage - reduced burning of fossil fuels
- By reducing the necessary temperatures and/or pressures, fewer fossil fuels need to be burned.
- This means that we can reduce our negative environmental impact.
Disadvantage - toxicity
Disadvantage - toxicity
- But, many catalysts are toxic (e.g. transition metals), and these can escape into the environment and contaminate ecosystems.
