The
cluster–nuclei coassembled strategy provides an impressive
way to obtain 1D subnanometer heteronanostructures, including subnanometer
nanowires and subnanometer nanobelts. These nanomaterials have diameters
and thicknesses close to the size of a unit cell and exhibit excellent
performance originating from multicomponent synergy. This Mini Review
summarizes the recent progress of these novel functional nanomaterials,
including their properties and applications in catalysis, energy conversion,
and other fields. On the basis of previous studies, the development
direction of cluster–nuclei coassembled 1D subnanometer materials
is pointed out.
