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.
