First of all, a rare earth existence diagram is given in Figure 45 for all the higher boride compounds discussed in this review. As noted before, size constraints on the voids which are created among the boron cluster networks result in different ranges of possible rare earth elements for the different compounds.

A heterogeneous catalyst that permits hydrogenation of an alkyne to an alkene is the nickel boride compound called P-2 catalyst. The P-2 catalyst can be prepared by the reduction of nickel acetate with sodium borohydride ... 

In this section, I focns on the ternary rare earth boride compounds that have particnlar interest for their stmctural features or physical properties. Rare earth borocarbides are described in a separate section, after the section on rare earth carbides.

An appropriate catalyst is necessary to carry out the hydrolysis reaction at a high rate. Noble metal based catalysts were initially developed and studied for this purpose [5, 12-15], but the high cost of these materials associated with the low supply available shifted the focus of research towards cheaper catalytic materials. In fact, non-noble metals that form boride compounds such as Ni-B or Co-B alloys are efficient and low-cost catalysts for this reaction [6, 8, 11, 12, 16-19].
