Several experiments were carried out in the CATLAB in order to
determine the hydrogen produced with different LSF731- and iron
oxide-containing OCMs and the stability of these materials over a
larger number of cycles. The sample (50 mg) was initially
pre-oxidised with 5% oxygen in helium. After that, 25 cycles using
5% carbon monoxide in helium during the reduction and 5% water
in helium during the oxidation were performed at 850 C and
1 atm.
