12 Claims

1. A standalone precursor for synthesizing boron nitride nanotubes, the standalone precursor comprising:

a pillar,

wherein:

pores are defined in the pillar;

through-holes are defined in the pillar;

a ratio of a diameter of the standalone precursor to a length of the standalone precursor is between 1:3 and 1:6, inclusive; and

each of the through-holes extends continuously from a first opening on an outer surface of the standalone precursor to a second opening on the outer surface of the standalone precursor, the first opening being diametrically opposite to the second opening across the standalone precursor.
