TOP is of low toxicity phosphorus source. Since TOP has a very strong coordination effect, the use of TOP can efficiently promote the reaction and create some
uncommon nanostructures. For example, Zhang et al. [39] successfully prepared
nanoporous FeP nanosheets via anion-exchange reaction of inorganic–organic
hybrid Fe 18 S 25 –TETAH (TETAH ¼ protonated triethylenetetramine) nanosheets
(Fig. 16.3). It is noted that low solubility of TOP in water and its high decomposition
temperature retard this system only to be finished in some high boiling point solvents
(octyl ether and 1-octadecylene), which leads to this reaction to be highly flammable
and corrosive. Besides, the TOP oxide (tri-n-octylphosphine oxide, TOPO) and
other organic phosphines (tri-phenylposphine, TPP) can play a similar role in
preparation of TMPs [40, 41].
