“…Compared to the metal chalcogenides, the phase control of metal pnictides in colloidal synthesis is far less studied even though they are important catalysts in oxygen reduction reactions and hydrogen evolution reactions. − Pnictides have a comparable number of phases to the chalcogenides; for example, there are ten nickel sulfides, seven nickel selenides, and nine nickel tellurides, while there are four nickel nitrides, ten nickel phosphides, and five nickel arsenides. , The lack of studies does not come from an absence of phases, but rather from synthetic challenges such as potentially dangerous reagents and extreme heat (700+ °C). , Many metal pnictides are important catalyst materials, , therefore, there is a large opportunity for growth in the area of phase control of the metal pnictides.…”

A fundamental precept of chemistry is that properties are manifestations of the elements present and their arrangement in space. Controlling the arrangement of atoms in nanocrystals is not well understood in nanocrystal synthesis, especially in the transition metal chalcogenides and pnictides, which have rich phase spaces. This Perspective will cover some of the recent advances and current challenges. The perspective includes introductions to challenges particular to chalcogenide and pnictide chemistry, the often-convoluted roles of bond dissociation energies and mechanisms by which precursors break down, using very organized methods to map the synthetic phase space, a discussion of polytype control, and challenges in characterization, especially for solving novel structures on the nanoscale and time-resolved studies.
