Small-Particle Platinum Catalysts
The highly uniform mesoporous aluminosil-icate (MCM-41) has excellent catalytic properties but has only recently been studied as a support material.
Now, however, researchers from Germany have synthesised platinum-containing MCM-41 catalysts via different techniques and tested their catalytic performance during the oxidation of carbon monoxide in air (J. Chem. Soc., Chem. Commun., 1995, (22), 2283–2284).
Catalyst performance depended on the preparation method. The best performance was achieved over platinum-MCM-41 prepared by incipient wetness, giving platinum particles of size around 2 nm, and 50 per cent carbon monoxide conversion at temperatures as low as 360 K.
