I am doing an acid and magnesium reaction for my A2 coursework, and wanted to use a catalyst to lower the activation energy. What would I use?

You could try adding a drop of copper(II) sulphate solution. This works for the reaction between zinc and acids, so I would expect it to have some effect on the equivalent magnesium reaction.
It works when the zinc displaces a little copper metal so that you now have two metals in contact with an electrolyte. This sets up a short-circuited cell which electrolyses itself.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
