Pretty much anything that reflects visible light; typical metallized
coatings reflect deep enough into the UV spectrum for your purposes.
Just make sure you get a front-surface mirror, though; the glass of
a rear-surface mirror isn't transparent to anything except near-UV.
Most telescope mirrors are front-coated, and should work fine.
