The metals, such as Fe, Cu and Co, which can be reduced by KBH〓, can not change the catalytic properties obviously if only small amount of them are added to Ni-B alloys; those who can not react with KBH〓, such as Zn〓, are washed out during the preparation, so they also can not change the catalytic properties; while addition of the elements in VIB group, such as Cr, Mo and W, can increase the hydrogenation activity magnificently.

同样，我们通过添加第三组分来修饰Ni-B合金，可以被还原的金属，如Fe、Co、Cu等，少量添加并不能明显改变其反应性能；而与KBH〓不发生反应的金属，如Zn，以离子形式加入后，除了少量离子被吸附在催化剂表面外，基本不残留在催化剂里，因此对反应性能也没有太大的改变；只有VIB族元素，如Cr、Mo、W的加入才会很大改进Ni-B催化剂在蒽醌加氢中的催化性能，尤以Cr的修饰作用最好。
