Abstract:
Metal composite membranes were prepared by sequential electroless plating technique. The prepared membrane were characterized by x-ray diffraction (XRD). Scanning electron microscopy (SEM) , energy dispersive spectroscopy and inductively coupled plasma atomic emission spectroscopy techniques (ICP-AES). Effects of annealing times, Ag content , and air treatment on the hydrogen permission flux and morphology of the alloys were investigatedshowed that the prepared type of tube had a good potential as substrate for membrane preparation . in addition of the uniform defect –free alloy was prepared by annealing at 550 o c in H2atmosphere. The permeation result showed an increased in H2 permeation flux by increasingthe Ag account and the annealing time. In addition the air treatment of the prepared membrane at 400oc for 1 h changed and morphology enhanced the hydrogen FLUX
