AB This paper reports on doping with the catalysts consist of rare metal compounds like Co&lt;sub&gt;2&lt;/sub&gt;B, La(NO&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;3&lt;/sub&gt;, Ce(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;, Ti(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;, CeCl&lt;sub&gt;3&lt;/sub&gt;, LaCl&lt;sub&gt;3&lt;/sub&gt; and mixed catalysts for improving hydrogen release capacity of NaBH&lt;sub&gt;4&lt;/sub&gt;. The results show that the hydrogen generation volume (HGV) is about 10ml and the hydrogen generation rate (HGR) is very low when doping with La(NO&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;3&lt;/sub&gt;, Ce(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;, Ti(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;, CeCl&lt;sub&gt;3&lt;/sub&gt; and LaCl&lt;sub&gt;3&lt;/sub&gt;. Comparatively, Co&lt;sub&gt;2&lt;/sub&gt;B presents favorable catalytic effect on hydrogen generation properties of NaBH&lt;sub&gt;4&lt;/sub&gt;. The study on the mixed catalysts find that the HGV of the samples doped with mixed catalyst of Co&lt;sub&gt;2&lt;/sub&gt;B and Ce(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt; is the largest. Among all doped samples, the HGV of sample doped with 5Co&lt;sub&gt;2&lt;/sub&gt;B\2Ce(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt; is the largest about 317ml. Compared to all samples doped with mixed catalysts, the samples doped with mixed catalysts of Co&lt;sub&gt;2&lt;/sub&gt;B, Ce(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;, Ti(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt; and CeCl&lt;sub&gt;3&lt;/sub&gt; presents the best properties of hydrogen release. However, compared to Co&lt;sub&gt;2&lt;/sub&gt;B, doping with other catalysts makes the hydrogen release time of NaBH&lt;sub&gt;4&lt;/sub&gt; longer. Overall, NaBH&lt;sub&gt;4&lt;/sub&gt; doped with the mixed catalysts of Co&lt;sub&gt;2&lt;/sub&gt;B, Ti(SO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt; and CeCl&lt;sub&gt;3&lt;/sub&gt; present the optimal HGV and HGR than doped with any other catalysts.
