E ffect of extended ball milling on graphite__

2011-2-12Conclusions Ball milling of graphite for up to 1000 h in vacuum lead to the formation of a highly reactive carbon which was found to chemisorb large amounts of carbon dioxide after exposure to air. The presence of CO 2 on the surface was con?rmed by FTIR and its removal during heating was demonstrated by TG–FTIR and FTIR of heated powders.Get price

Direct Mechanocatalysis: Using Milling Balls as

In general, the milling ball or vessel is made from a catalytically active component. This novel type of catalysis offers the advantage of directly using solid educts that do not require any solubility. Catalyst recycling and separation is most facile, as the macroscopic milling ball simply has to be taken out of the vessel after the reaction.Get price
