1

Why are catalysts used in many industrial processes?

They can help to reduce the energy and time needed for reactions, saves money and reduces impacts on environment

2

Why can using catalysts help if fossil fuels are burning?

Catalysts will help conserve resources and reduce pollution

3

What are traditional catalysts?

Transitional metals or their compounds

4

What is the downside to using traditional catalysts?

Some of the transitional metals and their compounds are toxic and may cause harm if they get into the environment

5

Why would enzymes be better than traditional catalysts in industry?

They work at lower temps so reduce energy costs even further

6

What is now becoming a new and exciting possibility for highly efficient catalysts?

Nanoparticles

7

Which 2 areas of research offer possibilities for new or better catalysts? Why?

•nanoparticles
•enzymes

They result in less waste, are safer for the environment and will reduce energy costs even further

8

Why are catalysts economic?

They don't need replacing very often
