Platinum catalysis is a surface effect so a form that maximizes
the surface is effective. One such preparation is platinum black -
made by vacuum drying. Platinum is used in fine wire gauze for
ammonium reactions, and carried on aluminum oxide grit for petroleum
cracking.
It is absorbed as an organometal or as a suspension into porous
material where heating drives off the carrier.
