摘要

氢中的杂质影响金属间化合物体系的储存能力。一氧化碳与含镍的金属间化合物如CaNi5相互作用,产生挥发性羰基镍,导致过渡金属含量下降,储氢能力下降,吸附动力学下降。本文用x射线光电子能谱(XPS)和吸附动力学数据研究了这些效应的意义。

Interaction of carbon monoxide with the hydrogen storage alloy, CaNi5; kinetic and surface studies

Impurities in hydrogen affect the storage capacity of intermetallic systems. Carbon monoxide interacts with nickel-containing intermetallics such as CaNi5 to give volatile nickel carbonyl which leads to a fall in the transition metal content, the hydrogen storage capacity and the sorption kinetics. The implications of these effects are investigated here by X-ray Photoelectron Spectroscopy (XPS) and sorption kinetic data.
