Abstract
Nanophase iron carbides can be obtained by high energy milling (mechan osynthesis). The hydrogenation of CO2 catalyzed by mechanosynthesized iron carbides (at different milling stages) is studied from the point of view of activity, selectivity and stability during the reaction. Th e catalytic properties are attractive and competitive with those of ot her catalytic materials. The catalytic behaviour is shown to be stable during testing for 24 h. Structural characterization of the catalysts after the reaction is also reported.
