That's a possibility but in order for your theory to be true you have to prove that the platinum-catalyzed decomposition is the rate limiting process. I think the supply of the pollutants may very well be the slowest step in an average archival storage condition. Anyway, the catalyst action of these metals can be significantly weakened by using an agent that acts as a "catalyst poison." -- Ryuji Suzuki "Patriotism is the last refuge to which a scoundrel clings."
