Abstract :
The interaction of hydrogen with LaNi3,5Cu1,5 — a catalyst for hydrogenation of organic compounds — was studied in a wide temperature range (308–373 K) by the Tian–Calvet differential heat-conduction calorimetry. The P–C–T-, Q–C–T-diagrams and the results of mathematical treatment of the calorimertic data are presented. The formation mechanism of active hydrogen solved in metal matrix is proposed.
