A new and powerful method for the synthesis of hydrogen storage materials
and monitoring of hydrogenation reactions by reactive ball milling
under high hydrogen atmosphere has been developed. It involves
high-energy ball milling in an especially designed vial, allowing
in-situ monitoring of temperature and, more importantly, of hydrogen
pressure by incorporating a newly developed gas-temperature measurement
system as well as a radio emitter into the vial lid. An external
receiver transmits the data to a data acquisition computer.
