所有含碳納米管的樣品在脫氫後都表現出相似的XRD圖譜。不存在殘餘氫化物

All samples containing carbon nanotubes showed similar XRD patterns after dehydrogenation. There is no residual hydride, which indicates that complete hydrogen has been released (Figure 4a). Figure 4b shows that both magnesium and magnesium hydroxide are present in the sample containing 5wt% graphene+2ml cyclohexane. It is inferred that the activation conditions in the experiment have less effect on the complete reduction of the alloy oxide layer than this additive. Research shows that high temperature can effectively reduce the oxide layer on the surface of magnesium alloy. The formation of oxide and hydroxide layers on the alloy surface greatly reduces the hydrogen absorption capacity. The same is true for other organic additives and hydrogenation conditions.

All samples containing carbon nanotubes showed similar XRD maps after dehydrogenation. There is no residual hydrogenation, indicating that complete hydrogen has been released (Figure 4a). Figure 4b shows the presence of magnesium and magnesium hydroxide in samples containing 5wt% graphene plus 2 ml of cyclohexane. It is speculated that the active conditions in the experiment are not as effective at reducing the alloy oxidation layer as the additive. The research shows that high temperature can effectively reduce the oxidation layer of magnesium alloy surface. The formation of alloy surface oxides and hydroxide layers greatly reduces hydrogen absorption capacity. The same is true for other organic additives and hydrogenation conditions.

All samples containing CNTs show similar XRD patterns after dehydrogenation. There is no residual hydride, which indicates that complete hydrogen has been released (FIG. 4A). Fig. 4B shows that magnesium and magnesium hydroxide exist simultaneously in the sample containing 5wt% graphene + 2ml cyclohexane. It is speculated that the effect of activation conditions on the complete reduction of alloy oxide layer is not as good as that of the additive. The results show that high temperature can effectively reduce the oxide layer on the surface of magnesium alloy. The formation of oxide and hydroxide layer on the alloy surface greatly reduces the hydrogen absorption capacity. The same is true for other organic additives and hydrogenation conditions.<br>
