摘要：

A doping of 5 wt% CoCl(2) considerably decreases the dehydrogenation temperature of a mixture of LiNH(2) and LiBH(4). More that 8 wt% of hydrogen can be released at ca. 155 degrees C. X-Ray absorption near edge structure (XANES) spectroscopy indicated the formation of metallic Co after ball milling CoCl(2) with LiNH(2) and LiBH(4). Extended X-ray absorption fine structure (EXAFS) spectroscopy measurements revealed that Co particles have poor crystallinity and are finely dispersed in the sample, which could lead to a high catalytic efficiency.
