I guess they were trying for an IgNobel Prize? However, they don't report anything on the stability of the catalyst under reaction conditions, that is how many reaction cycles it goes through before losing catalytic effect.

If they don't report the lifetime, it's usually because the lifetime is crap, and all they have is a laboratory curiousity - which might, with futher diligent effort (and please, another research grant!), become industrially useful... maybe.
