This article describes a Group (VI) modified Co-Zr-B amorphous nano alloys were prepared in situ ultrasound-assisted reduction by sodium borohydride in an aqueous solution. Co-Cr-Zr-B, Co-Mo-Zr-B and Co-W-Zr-B powders were characterized by XRD, FESEM, BET and ICP techniques. No distinct peak...

Recently, interest in chemical-looping combustion (CLC) has grown because it is a technique that could allow cost-effective carbon capture and storage. Recently, the chemical-looping process was also proposed for the production of hydrogen. Chemical-looping hydrogen (CLH) generation, which is a...
